s390x: move fpu regs into a subsection of the vmstate
Let's move the floating point registers into a seperate subsection and
bump up the version id. This cleans up the current vmstate and will
allow for a future extension with vector registers in a compatible way.
This patch is based on a patch from Eric Farman.
