efi: Do not include <linux/screen_info.h> from EFI header

The header file <linux/efi.h> does not need anything from
<linux/screen_info.h>. Declare struct screen_info and remove
the include statements. Update a number of source files that
require struct screen_info's definition.

v2:
	* update loongarch (Jingfeng)
