[PATCH 03/16] efi: mode: add efi_get_runtime_services helper

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Similarly to the existing efi_get_boot_services() helper that replaces
hardcoded BS use to allow code to be usable from both payload and
upcoming loader support, efi_get_runtime_services() can replace RT use.
