x86/efi: Push EFI_MEMMAP check into leaf routines
In preparation for adding another EFI_MEMMAP dependent call that needs to occur before e820__memblock_setup() fixup the existing efi calls to check for EFI_MEMMAP internally. This ends up being cleaner than the alternative of checking EFI_MEMMAP multiple times in setup_arch().
