powerpc/kuap: Use MMU_FTR_KUAP on all and refactor disabling kuap
All but book3s/64 use a static branch key for disabling kuap.
book3s/64 uses an mmu feature.
Refactor all targets to use MMU_FTR_KUAP like book3s/64.
For PPC32 that implies updating mmu features fixups once KUAP
has been initialised.
