[PATCH] powerpc/mm: Desintegrate MMU_FTR_PPCAS_ARCH_V2

[Christophe Leroy]

MMU_FTR_PPCAS_ARCH_V2 is defined in cpu_table.h
as MMU_FTR_TLBIEL | MMU_FTR_16M_PAGE.

MMU_FTR_TLBIEL and MMU_FTR_16M_PAGE are defined in mmu.h

MMU_FTR_PPCAS_ARCH_V2 is used only in mmu.h and it is used only once.

Remove MMU_FTR_PPCAS_ARCH_V2 and use
directly MMU_FTR_TLBIEL | MMU_FTR_16M_PAGE
