Merged ppc_asm.h between ppc32 & ppc64.  The majority of the file is
common between the two architectures excluding how a single GPR is
saved/restored and which GPRs are non-volatile.

Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h.

Remove the CPU_FTR_PMC8 feature now we encode the number of PMCs
directly.

The firmware_features field of struct cpu_spec should really be a separate
variable as the firmware features do not depend on the chip and the
bitmask is constructed independently.  By removing it, we save 112 bytes
from the cpu_specs array and we access the bitmask directly instead of via
the cur_cpu_spec pointer.

Not all ppc64 CPUs have the CTRL SPR, so we need a cputable feature for it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
