PPC: Bring EPR support closer to reality

We already used to support the external proxy facility of FSL MPICs,

This patch adds support for

ppc: Move load and store helpers, switch to AREG0 free mode

Add an explicit CPUPPCState parameter instead of relying on AREG0
and rename op_helper.c (which only contains load and store helpers)
to mem_helper.c. Remove AREG0 swapping in
tlb_fill().

Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation...
