  target-ppc: KVMPPC_H_CAS fix cpu-version endianess

During KVMPPC_H_CAS processing, the cpu-version updated value is stored
without taking care of the current endianess. As a consequence, the guest
may not switch to the right CPU model, leading to unexpected results.

If needed, the value is now converted.

  target-ppc: Change default cpu for ppc64le-linux-user

The default, 970fx, doesn't support MSR_LE.  So even though we set LE in
ppc_cpu_reset, it gets cleared again in hreg_store_msr.  Error out if a
user-selected cpu model doesn't support LE.

The bswap that's needed for system mode isn't required for
user mode, and in fact breaks debugging.

  PPC: Fix booke206 TLB with phys addrs > 32bit

We were truncating physical addresses to 32bit when using qemu-system-ppc
with a booke206 TLB implementation. This patch fixes that and makes the full
address space available.

  target-ppc: Add pvr_match() callback

So far it was enough to have a base PVR value and mask per CPU
family such as POWER7 or POWER8. However there CPUs which are
completely architecturally compatible but have different PVRs such
as POWER7/POWER7+ and POWER8/POWER8E. For these CPUs, top 16 bits
are CPU family and low 16 bits are the version. The families have
PVR base values different enough so defining a mask which
would cover both (or potentially more) CPUs within the family is
not possible.

This adds a pvr_match() callback to PowerPCCPUClass. The default
handler simply compares PVR defined in the class.

This implements ppc_pvr_match_power7/ppc_pvr_match_power8 callbacks
for POWER7/8 families. These check for POWER7/POWER7+ and POWER8/POWER8E.

This changes ppc_cpu_compare_class_pvr_mask() not to check masks but
use the pvr_match() callback.

Since all server CPUs use the same mask, this defines one mask
value - CPU_POWERPC_POWER_SERVER_MASK - which is used everywhere now.
This removes other mask definitions.

This removes pvr_mask from PowerPCCPUClass as it is not used anymore.
This removes pvr initialization for POWER7/8 families as it is not used
to find the class, the pvr_match() callback is used instead.

  target-ppc: Remove POWER7+ and POWER8E families

POWER8E is architecturally equal to POWER8 and POWER7+ is equal to
POWER7. Also no user space tool makes any difference for CPU node name
in the device tree (such as PowerPC,address@hidden vs. PowerPC,address@hidden).
So there is no point in emulating POWER7+ and POWER8E apart from POWER7
and POWER8. Also, the previos patch implemented multiple PVR mask support
per CPU class so POWER7 class now covers both POWER7 and POWER7+ CPUs,
same is valid for POWER8/8E.

This removes POWER7+ and POWER8E classes. This replaces references
to POWER7P/POWER8E families with POWER7/POWER8 families.

Patch queue for ppc - 2014-07-08

A few bug fixes for 2.1:

  - Fix e500* TLB emulation with qemu-system-ppc
  - Update SLOF to current upstream (good number of bugfixes)
  - Make POWER7 / POWER8 PVR match more agnostic (needed in 2.1 for cmdline 
compat)
  - Fix u-boot.e500 install (how did that happen?)
  - Fix H_CAS on LE hosts
  - ppc64le-linux-user fixes
