KVM: x86: Move FPU register accessors into fpu.h

Browse source

Hyper-v XMM fast hypercalls use XMM registers to pass input/output
parameters. To access these, hyperv.c can reuse some FPU register
accessors defined in emulator.c. Move them to a common location so both
can access them.

While at it, reorder the parameters of these accessor methods to make
them more readable.
