[PATCH 1/2] x86/efi-bgrt: Move efi-bgrt handling out of arch/x86

[Bhupesh Sharma]

Now with open-source boot firmware (EDK2) supporting ACPI BGRT table addition
even for architecures like AARCH64, it makes sense to move out the 'efi-bgrt.c'
file and supporting infrastructure from 'arch/x86' directory and house it
inside 'drivers/firmware/efi', so that this common code can be used accross
architecures.

This patch (1) of a series having (2) patches, prepares the background
so that handling of ACPI BGRT tables and BGRT image can be added
in other architectures.
