[PATCH 32/40] arm64/efi: Move to generic {__,}efi_call_virt

[Matt Fleming <matt-mF/unelCI9GS6iBeEJttW/XRex20P6io@public.gmane.org>]

From: Mark Rutland <mark.rutland-5wv7dgnIgG8@public.gmane.org>

Now there's a common template for {__,}efi_call_virt, remove the
duplicate logic from the arm64 efi code.
