efi: fix prototype for API stubs

Some functions in the efi API have recently been added as versions for non-x86,
but are missing an "inline" keyword, which causes these warnings:

include/linux/efi.h:503:13: error: 'efi_enter_virtual_mode' defined but not used [-Werror=unused-function]
include/linux/efi.h:504:13: error: 'efi_late_init' defined but not used [-Werror=unused-function]
include/linux/efi.h:505:13: error: 'efi_free_boot_services' defined but not used [-Werror=unused-function]
