x86/efi/bgrt: Move efi-bgrt handling out of arch/x86

Now with open-source boot firmware (EDK2) supporting ACPI BGRT table
addition even for architectures 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 across architectures.
