ppc/pnv: POWER9 XSCOM quad support

The POWER9 processor does not support per-core frequency control. The
cores are arranged in groups of four, along with their respective L2
and L3 caches, into a structure known as a Quad. The frequency must be
managed at the Quad level.

Provide a basic Quad model to fake the settings done by the firmware
on the Non-Cacheable Unit (NCU). Each core pair (EX) needs a special
BAR setting for the TIMA area of XIVE because it resides on the same
address on all chips.

ppc/pnv: add a XIVE interrupt controller model for POWER9

This is a simple model of the POWER9 XIVE interrupt controller for the
PowerNV machine which only addresses the needs of the skiboot
firmware. The PowerNV model reuses the common XIVE framework developed
for sPAPR as the fundamentals aspects are quite the same. The
difference are outlined below.

The controller initial BAR configuration is performed using the XSCOM
bus from there, MMIO are used for further configuration.

The MMIO regions exposed are :

- Interrupt controller registers
- ESB pages for IPIs and ENDs
- Presenter MMIO (Not used)
- Thread Interrupt Management Area MMIO, direct and indirect

The virtualization controller MMIO region containing the IPI ESB pages
and END ESB pages is sub-divided into "sets" which map portions of the
VC region to the different ESB pages. These are modeled with custom
address spaces and the XiveSource and XiveENDSource objects are sized
to the maximum allowed by HW. The memory regions are resized at
run-time using the configuration of EDT set translation table provided
by the firmware.

The XIVE virtualization structure tables (EAT, ENDT, NVTT) are now in
the machine RAM and not in the hypervisor anymore. The firmware
(skiboot) configures these tables using Virtual Structure Descriptor
defining the characteristics of each table : SBE, EAS, END and
NVT. These are later used to access the virtual interrupt entries. The
internal cache of these tables in the interrupt controller is updated
and invalidated using a set of registers.

Still to address to complete the model but not fully required is the
support for block grouping. Escalation support will be necessary for
KVM guests.

spapr: modify the prototype of the cpu_intc_create() method

Today, the interrupt presenter is linked to a CPU using the
cpu_intc_create() method of the sPAPR IRQ backend. The resulting
object is assigned to the PowerPCCPU 'intc' pointer whatever the
interrupt mode, XICS or XIVE.

To support the 'dual' interrupt mode, we will need to distinguish
between the two presenter objects and for that, we plan to introduce a
second interrupt presenter object pointer under the PowerPCCPU. The
modifications below move the assignment of the presenter object under
the cpu_intc_create() method to prepare ground for the future changes.

Both sPAPR and PowerNV machines are impacted.

* The biggest set here is the ppc parts of Igor Mammedov's cleanups
to cpu model handling
* The above also includes a generic patches which are required as
prerequisites for the ppc parts. They don't seem to have been
merged by Eduardo yet, so I hope they're ok to include here.
* Apart from that it's basically just assorted bug fixes and cleanups

ppc: pnv: drop PnvChipClass::cpu_model field

deduce core type directly from chip type instead of
maintaining type mapping in PnvChipClass::cpu_model.
