[PATCH V2] arm64/mm: Drop <asm/page-def.h>

[Anshuman Khandual]

PAGE_SHIFT (PAGE_SIZE and PAGE_MASK) which is derived from ARM64_PAGE_SHIFT
should be moved into <asm/page.h> instead like in case for other platforms,
and then subsequently <asm/page-def.h> can be just dropped off completely.

This applies on 5.14-rc6.

Changes in V2:

- Moved PAGE_XXX macros into <asm/page.h> instead of <asm/pgtable-hwdef.h>
- Changed the commit message accordingly
