powerpc/mm/radix: Add MMU_FTR_RADIX
We are going to add asm changes in the follow up patches. Add the
feature bit now so that we can get it all build.
mpe: When CONFIG_PPC_RADIX_MMU=n we omit MMU_FTR_RADIX from the
MMU_FTRS_POSSIBLE mask. This allows the compiler to work out that those
checks will always be false and so the code can be elided completely.
Note we do *not* define MMU_FTR_RADIX to 0 in the RADIX_MMU=n case,
because that doesn't work with the ASM_FTR patching. In particular an
IF_SET section will result in a mask and value of zero, which is always
true, meaning the section *won't* be patched, which is the opposite of
what we want.
