target/arm: Make vfp_set_fpscr() call vfp_set_{fpcr, fpsr}

Make vfp_set_fpscr() call vfp_set_fpsr() and vfp_set_fpcr()
instead of the other way around.

The masking we do when getting and setting vfp.xregs[ARM_VFP_FPSCR]
is a little awkward, but we are going to change where we store the
underlying FPSR and FPCR information in a later commit, so it will
go away then.
