[PATCH] powerpc/mm: Use tlbiel for 4KB pages

[Gavin Shan]

The firmware should have supplied correct information for the kernel
to figure out the page size array, which is traced by mmu_psize_defs[].
Otherwise, the kernel will fail back to use solely 4KB page size
and copy mmu_psize_defaults_old[] over to mmu_psize_defs[]. However,
the "tlbiel" isn't enabled in mmu_psize_defaults_old[].
