ARM: imx: Use USB SDPS as fallback option on Data Modul i.MX8M Plus eDM SBC

The Data Modul i.MX8M Plus eDM SBC does have USB gadget capable port
accessible via USB A-A cable plugged into the bottom USB 3.0 port.
Use USB SDPS as the fallback boot device, so USB SDPS loading can
be performed using e.g. uuu tool.
