KVM: PPC: Separate loadstore emulation from priv emulation
Today the instruction emulator can get called via 2 separate code paths. It can either be called by MMIO emulation detection code or by privileged instruction traps. This is bad, as both code paths prepare the environment differently. For MMIO emulation we already know the virtual address we faulted on, so instructions there don't have to actually fetch that information. Split out the two separate use cases into separate files.
