arm64: efi: Switch to our own stack

We don't want to map EFI_BOOT_SERVICES_DATA regions, so move the
stack from its EFI_BOOT_SERVICES_DATA region to EFI_LOADER_CODE,
which we always map. We'll still map the stack as R/W instead of
R/X because we split EFI_LOADER_CODE regions on the _etext boundary
and map addresses before _etext as R/X and the rest as R/W.
