fix(rdv3): correctly handle FP regs context saving

Commit fe488c3796e01187fb6cffdd27a1bee1a33e0931 added an override to
force `CTX_INCLUDE_SVE_REGS` to 0 when `SPD == spmd` and
`SPMD_SPM_AT_SEL2 == 1`.
Since there is an architectural dependency between FP and SVE registers,
`CTX_INCLUDE_FPREGS` must also be overridden to 0 when
CTX_INCLUDE_SVE_REGS is 0.
