hw/arm/smmu-common: Support nested translation

When nested translation is requested, do the following:
- Translate stage-1 table address IPA into PA through stage-2.
- Translate stage-1 table walk output (IPA) through stage-2.
- Create a single TLB entry from stage-1 and stage-2 translations
using logic introduced before.

smmu_ptw() has a new argument SMMUState which include the TLB as
stage-1 table address can be cached in there.

Also in smmu_ptw(), a separate path used for nesting to simplify the
code, although some logic can be combined.

With nested translation class of translation fault can be different,
from the class of the translation, as faults from translating stage-1
tables are considered as CLASS_TT and not CLASS_IN, a new member
"is_ipa_descriptor" added to "SMMUPTWEventInfo" to differ faults
from walking stage 1 translation table and faults from translating
an IPA for a transaction.

hw/arm/smmu-common: Add support for nested TLB

This patch adds support for nested (combined) TLB entries.
The main function combine_tlb() is not used here but in the next
patches, but to simplify the patches it is introduced first.

Main changes:
1) New field added in the SMMUTLBEntry struct: parent_perm, for
nested TLB, holds the stage-2 permission, this can be used to know
the origin of a permission fault from a cached entry as caching
the “and” of the permissions loses this information.

SMMUPTWEventInfo is used to hold information about PTW faults so
the event can be populated, the value of stage used to be set
based on the current stage for TLB permission faults, however
with the parent_perm, it is now set based on which perm has
the missing permission

When nesting is not enabled it has the same value as perm which
doesn't change the logic.

2) As combined TLB implementation is used, the combination logic
chooses:
- tg and level from the entry which has the smallest addr_mask.
- Based on that the iova that would be cached is recalculated.
- Translated_addr is chosen from stage-2.

hw/arm/smmu: Consolidate ASID and VMID types

ASID and VMID used to be uint16_t in the translation config, however,
in other contexts they can be int as -1 in case of TLB invalidation,
to represent all (don’t care).
When stage-2 was added asid was set to -1 in stage-2 and vmid to -1
in stage-1 configs. However, that meant they were set as (65536),
this was not an issue as nesting was not supported and no
commands/lookup uses both.

With nesting, it’s critical to get this right as translation must be
tagged correctly with ASID/VMID, and with ASID=-1 meaning stage-2.
Represent ASID/VMID everywhere as int.

hw/arm/smmu: Split smmuv3_translate()

smmuv3_translate() does everything from STE/CD parsing to TLB lookup
and PTW.

Soon, when nesting is supported, stage-1 data (tt, CD) needs to be
translated using stage-2.

Split smmuv3_translate() to 3 functions:

- smmu_translate(): in smmu-common.c, which does the TLB lookup, PTW,
TLB insertion, all the functions are already there, this just puts
them together.
This also simplifies the code as it consolidates event generation
in case of TLB lookup permission failure or in TT selection.

- smmuv3_do_translate(): in smmuv3.c, Calls smmu_translate() and does
the event population in case of errors.

- smmuv3_translate(), now calls smmuv3_do_translate() for
translation while the rest is the same.

Also, add stage in trace_smmuv3_translate_success()

hw/arm/smmu: Use enum for SMMU stage

Currently, translation stage is represented as an int, where 1 is stage-1 and
2 is stage-2, when nested is added, 3 would be confusing to represent nesting,
so we use an enum instead.

While keeping the same values, this is useful for:
- Doing tricks with bit masks, where BIT(0) is stage-1 and BIT(1) is
stage-2 and both is nested.
- Tracing, as stage is printed as int.

hw/arm/smmuv3: Parse STE config for stage-2

Parse stage-2 configuration from STE and populate it in SMMUS2Cfg.
Validity of field values are checked when possible.

Only AA64 tables are supported and Small Translation Tables (STT) are
not supported.

According to SMMUv3 UM(IHI0070E) "5.2 Stream Table Entry": All fields
with an S2 prefix (with the exception of S2VMID) are IGNORED when
stage-2 bypasses translation (Config[1] == 0).

Which means that VMID can be used(for TLB tagging) even if stage-2 is
bypassed, so we parse it unconditionally when S2P exists. Otherwise
it is set to -1.(only S1P)

As stall is not supported, if S2S is set the translation would abort.
For S2R, we reuse the same code used for stage-1 with flag
record_faults. However when nested translation is supported we would
need to separate stage-1 and stage-2 faults.

Fix wrong shift in STE_S2HD, STE_S2HA, STE_S2S.

In preparation for adding stage-2 support, rename smmu_ptw_64 to
smmu_ptw_64_s1 and refactor some of the code so it can be reused in

Remove AA64 check from PTW as decode_cd already ensures that AA64 is
used, otherwise it faults with C_BAD_CD.

A stage member is added to SMMUPTWEventInfo to differentiate
between stage-1 and stage-2 ptw faults.

hw/arm/smmuv3: Update translation config to hold stage-2

In preparation for adding stage-2 support, add a S2 config
struct(SMMUS2Cfg), composed of the following fields and embedded in
the main SMMUTransCfg:
-tsz: Size of IPA input region (S2T0SZ)
-sl0: Start level of translation (S2SL0)
-affd: AF Fault Disable (S2AFFD)
-record_faults: Record fault events (S2R)
-granule_sz: Granule page shift (based on S2TG)
-vmid: Virtual Machine ID (S2VMID)
-vttb: Address of translation table base (S2TTB)
-eff_ps: Effective PA output range (based on S2PS)

They will be used in the next patches in stage-2 address translation.

The fields in SMMUS2Cfg, are reordered to make the shared and stage-1
fields next to each other, this reordering didn't change the struct
size (104 bytes before and after).

Stage-1 only fields: aa64, asid, tt, ttb, tbi, record_faults, oas.
oas is stage-1 output address size. However, it is used to check
input address in case stage-1 is unimplemented or bypassed according
to SMMUv3 manual IHI0070.E "3.4. Address sizes"

Shared fields: stage, disabled, bypassed, aborted, iotlb_*.

No functional change intended.
