efi: sysfb_efi: fix build when EFI is not set

When # CONFIG_EFI is not set, there are 2 definitions of
sysfb_apply_efi_quirks(). The stub from sysfb.h should be used
and the __init function from sysfb_efi.c should not be used.

../drivers/firmware/efi/sysfb_efi.c:337:13: error: redefinition of ‘sysfb_apply_efi_quirks’
 __init void sysfb_apply_efi_quirks(struct platform_device *pd)
             ^~~~~~~~~~~~~~~~~~~~~~
In file included from ../drivers/firmware/efi/sysfb_efi.c:26:0:
../include/linux/sysfb.h:65:20: note: previous definition of ‘sysfb_apply_efi_quirks’ was here
 static inline void sysfb_apply_efi_quirks(struct platform_device *pd)
                    ^~~~~~~~~~~~~~~~~~~~~~
