[AArch64] Remove unneeded FSUB alternatives and add a new one

subtraction of constants, since those go through the addition
patterns instead. There was a missing MOVPRFX alternative for
FSUBR though.

* config/aarch64/aarch64-sve.md (*sub<SVE_F:mode>3): Remove immediate
FADD and FSUB alternatives. Add a MOVPRFX alternative for FSUBR.
