Revert "board: verdin-am62: allow dfu update"

Drop the the dfu update possibility in favour of a follow up
Toradex Easy Installer procedure.

This reverts commit 6d147efd19e42b03b812392c4bf8eee4e96b2d2d.

Upstream-Status: Pending

Initial U-Boot to be used for bring-up and validation of the V1.0
design, we'll decide on the step forward to mainline this once the
bring-up and validation will be done.
