KVM: PPC: Enable MMIO to do 64 bits, fprs and qprs
Right now MMIO access can only happen for GPRs and is at most 32 bit wide.
That's actually enough for almost all types of hardware out there.
Unfortunately, the guest I was using used FPU writes to MMIO regions, so
it ended up writing 64 bit MMIOs using FPRs and QPRs.
So let's add code to handle those odd cases too.
