KVM: PPC: Reimplement non-SIMD LOAD/STORE instruction mmio emulation with analyse_instr() input

Browse Source 
This patch reimplements non-SIMD LOAD/STORE instruction MMIO emulation
with analyse_instr() input. It utilizes the BYTEREV/UPDATE/SIGNEXT
properties exported by analyse_instr() and invokes
kvmppc_handle_load(s)/kvmppc_handle_store() accordingly.

It also moves CACHEOP type handling into the skeleton.

instruction_type within kvm_ppc.h is renamed to avoid conflict with
sstep.h.
