efi/bgrt: Enable ACPI BGRT handling on arm64
Now that the ACPI BGRT handling code has been made generic, we can
enable it for arm64.
Signed-off-by: Bhupesh Sharma <bhsharma@redhat.com>
[ Updated commit log to reflect that BGRT is only enabled for arm64, and added
missing 'return' statement to the dummy acpi_parse_bgrt() function. ]
