KVM: PPC: Book3S: Add MMIO emulation for VMX instructions
This patch provides the MMIO load/store vector indexed
X-Form emulation.
Instructions implemented:
lvx: the quadword in storage addressed by the result of EA &
0xffff_ffff_ffff_fff0 is loaded into VRT.
stvx: the contents of VRS are stored into the quadword in storage
addressed by the result of EA & 0xffff_ffff_ffff_fff0.
