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.

These names seem too generic to belong in asm/kvm.h - some
application could use the same names. Please add a KVM_ prefix.
Yes, will do.
