powerpc/mm: Unify PTE_RPN_SHIFT and _PAGE_CHG_MASK definitions This updates the 32-bit headers to use the same definitions for the RPN shift inside the PTE as 64-bit, and thus updates _PAGE_CHG_MASK to become identical. This does introduce a runtime visible difference, which is that now, _PAGE_HASHPTE will be part of _PAGE_CHG_MASK and thus preserved. However this should have no practical effect as it should have been preserved in the first place and we got away with not having it there due to our PTE access functions preserving it anyway.
