xen/arm64: Correctly align VFP regs

On arm64, VFP instructions requires vfpregs to be 128-byte aligned.

By chance, the field is already correctly aligned. In the case if someone
decides to add a new field before, Xen will receive a data abort as soon as
it saves/restores VFP.

We are safe on arm32 as the only constraint is to be 32-byte aligned.
