arm64: reorganise PAGE_/PROT_ macros

Browse source

Make these macros available to assembly code, so they can be re-used by the
PIE initialisation code.

This involves adding some extra macros, prepended with _ that are the raw
values not `pgprot` values.

A dummy value for PTE_MAYBE_NG is also provided, for use in assembly.
