3adfb457b8 powerpc/64e: Remove MMU_FTR_USE_TLBRSRV and MMU_FTR_USE_PAIRED_MAS 
Commit fb5a515704d7 ("powerpc: Remove platforms/wsp and associated
pieces") removed the last CPU having features MMU_FTRS_A2 and
commit cd68098bcedd ("powerpc: Clean up MMU_FTRS_A2 and
MMU_FTR_TYPE_3E") removed MMU_FTRS_A2 which was the last user of
MMU_FTR_USE_TLBRSRV and MMU_FTR_USE_PAIRED_MAS.

Remove all code that relies on MMU_FTR_USE_TLBRSRV and
MMU_FTR_USE_PAIRED_MAS.

With this change done, TLB miss can happen before the mmu feature
fixups.

Move FSL_BOOK3E version of update_mmu_cache() at the same
place as book3e_hugetlb_preload() as update_mmu_cache() is
the only user of book3e_hugetlb_preload().

3dea7332cc powerpc/book3e: hugetlbpage is only for CONFIG_PPC_FSL_BOOK3E 
As per Kconfig.cputype, only CONFIG_PPC_FSL_BOOK3E gets to
select SYS_SUPPORTS_HUGETLBFS so simplify accordingly.
