powerpc: Cleanup SPR and MSR definitions

Move SPR and MSR defines out of ppc_asm.h and processor.h and into a
new include, asm/reg.h.

Add a define for the PVR SPR and various processor versions, and replace
the open coded numbers in the sprs.c test case.

powerpc: Add support for more interrupts including HV interrupts

Interrupt vectors were not being populated for all architected
interrupt types, which could lead to crashes rather than a message for
unhandled interrupts.

0x20 sized vectors require some reworking of the code to fit. This
also adds support for HV / HSRR type interrupts which will be used in
a later change.

powerpc: Abstract H_CEDE calls into a sleep functions

This consolidates several implementations, and it no longer leaves
MSR[EE] enabled after the decrementer interrupt is handled, but
rather disables it on return.

The handler no longer allows a continuous ticking, but rather dec
has to be re-armed and EE re-enabled (e.g., via H_CEDE hcall) each
time.

powerpc: Fix running the kvm-unit-tests with recent versions of QEMU

Starting with version 7.0, QEMU starts the pseries guests in 32-bit mode
instead of 64-bit (see QEMU commit 6e3f09c28a - "spapr: Force 32bit when
resetting a core"). This causes our test_64bit() in powerpc/emulator.c
to fail. Let's switch to 64-bit in our startup code instead to fix the
issue.

powerpc: select endianness

This patch allows to build tests for ppc64 little endian target
(ppc64le) on big and little endian hosts.

We add a new parameter to configure to select the endianness of the
tests (--endian=little or --endian=big).

I have built and tested big and little endian tests on a little
endian host, a big endian host, with kvm_hv and kvm_pr, and on
x86_64 with ppc64 as a TCG target.
