Update to support EFI runtime outside the kernel virtual address space
by creating an EFI RT pmap that can be activated / deactivated when
required.

Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines.

On Arm64 the usage of pmapboot_enter is reduced and the mappings are
created much later in the boot process -- now in cpu_startup_hook.
Backward compatiblity for KVA mapped RT from old bootaa64.efi is
maintained.

Adding support to other platforms should be easier as a result.
