target-arm: A64: provide functions for accessing FPCR and FPSR

The information which AArch32 holds in the FPSCR is split for
AArch64 into two logically distinct registers, FPSR and FPCR.
Since they are carefully arranged to use non-overlapping bits,
we leave the underlying state in the same place, and provide
accessor functions which just update the appropriate bits
via vfp_get_fpscr() and vfp_set_fpscr().
