imx: kontron-sl-mx8mm: Enable SDP support for loading via USB

Browse Source 
Enable everything that is required to load via USB. The SPL needs
SDP support so it can load the U-Boot proper image via USB after
it has been loaded via serial loader mode of the i.MX.

This way we can use the uuu tool for loading SPL and U-Boot
proper like this:

  uuu -brun flash.bin
