powerpc/mm: Add early_[cpu|mmu]_has_feature()
In later patches, we will be switching CPU and MMU feature checks to
use static keys.
For checks in early boot before jump label is initialized we need a
variant of [cpu|mmu]_has_feature() that doesn't use jump labels.
So create those called, unimaginatively, early_[cpu|mmu]_has_feature().
