Make the conversion to driver model as it is mandatory.

Successfully tested booting Linux from the SD card.

Dropped splash screen support as this needs to be properly
converted to DM and tested.

I would like to help supporting this board, so add myself
as a maintainer.

Now that the board has been converted to DM, also add
its devicetree in the MAINTAINERS files entry.
