Move the kernel pagetable (both swapper and idmap) definitions
from the generic asm/page.h to a new file, asm/kernel-pgtable.h.
This is mostly a cosmetic change, to clean up the asm/page.h to

At the moment, we only support maximum of 3-level page table for
swapper. With 48bit VA, 64K has only 3 levels and 4K uses section
mapping. Add support for 4-level page table for swapper, needed
by 16K pages.

Now that we can calculate the number of levels required for

Rearrange the code for fake pgd handling, which is applicable
to only ARM64. The intention is to keep the common code cleaner,
unaware of the underlying hacks.

{V}TCR_EL2_TG0 is a 2bit wide field, where:
00 - 4K
01 - 64K
10 - 16K
But we use only 1 bit, which has worked well so far since
we never cared about 16K. Fix it for 16K support.

This patch doesn't remove sb_writers-wait_unfrozen yet, we keep
