KVM: MIPS/T&E: Treat unhandled guest KSeg0 as MMIO
Treat unhandled accesses to guest KSeg0 as MMIO, rather than only host
KSeg0 addresses. This will allow read only memory regions (such as the
Malta boot flash as emulated by QEMU) to have writes (before reads)
treated as MMIO, and unallocated physical addresses to have all accesses
treated as MMIO.
The MMIO emulation uses the gva_to_gpa callback, so this is also updated
for trap & emulate to handle guest KSeg0 addresses.
