The am62x config currently doesn't enable distroboot as an option for
booting. Add this as a further option after the existing mechanisms have
failed.

Whilst working on this it was found that boot detection was failing on
the am625-sk when attempting to boot from raw offsets on an SD card.
Boot mode is updated to correctly detect the boot mode from the SoC boot
config.

I'm excited to start getting rid of these custom boot scripts

I was looking at 'Standard Boot'[0] as my solution :)
