Subject: [PATCH tip/efi-kexec] x86: setup.c build fix

In case without CONFIG_EFI, there will be below build error:
   arch/x86/built-in.o: In function `setup_arch':
>> (.init.text+0x9dc): undefined reference to `parse_efi_setup'

Thus fix it by adding blank inline function in asm/efi.h
Also remove an unused declaration for variable efi_data_len.
