7985cdf74b arm64: Remove non-full-va map code
By now the code to only have a single page table level with 64k page
size and 42 bit address space is no longer used by any board in tree,
so we can safely remove it.

To clean up code, move the layerscape mmu code to the new defines,
removing redundant field definitions.

94f7ff36e5 armv8: New MMU setup code allowing to use 48+ bits PA/VA
This patch adds code which sets up 2-level page tables on ARM64 thus
extending available VA space. CPUs implementing 64k translation
granule are able to use direct PA-VA mapping of the whole 48 bit
address space.
It also adds the ability to reset the SCTRL register at the very beginning
of execution to avoid interference from stale mappings set up by early
firmware/loaders/etc.
