[PATCH v1] board: toradex: verdin-imx8mm: enable usb sdp spl recovery support

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Enable USB SDP SPL aka serial downloader recovery mode support.

While at it also enable fastboot support which may be used to
subsequently load further stages like a Toradex Easy Installer FIT
image.
