imx: imx8mm-beacon: Enable USB booting via SDP
In order to boot over USB, the device tree needs to enable
a few extra nodes in SPL. Since the USB driver has the
ability to detect host/device, the dr_mode can be removed
from the device tree since it needs to act as a device when
booting and OTG is the default mode. Add USB boot support
to spl_board_boot_device and enable the corresponding config
options.
