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.
