Series Boot-time page size selection for arm64 | expand

Commit Message

To prepare for supporting boot-time page size selection, refactor code
to remove assumptions about PAGE_SIZE being compile-time constant. Code
intended to be equivalent when compile-time page size is active.

Convert a CPP conditional to a C conditional. The compiler will dead
code strip when doing a compile-time page size build, for the same end
effect. But this will also work with boot-time page size builds.
