ARM: imx: Replace YModem with SDP on Data Modul i.MX8M Mini eDM SBC SPL
The YModem support in SPL was never really used on this device,
the SDP support is much more convenient on i.MX8M Mini based
hardware. Replace the YModem support with SDP support.
The SDP can be utilized by forcing the board into SDP boot mode
by grounding test point right next to silkscreen label U30, and
then by using mfgtools 'uuu -brun spl flash.bin' once the device
enumerates on host system USB bus. The SDP capable USB port is
available on the USB micro-B port on the base board.
