description:
Workaround a bug with ROCKPro64's U-Boot EFI implementation. The booted
device path when booting from SD card sometimes does not include a
MEDIA_DEVICE_PATH component, so in this case fallback to doing an exact
match on the booted device path with the block device path to detect the
default boot device.
