differ from the Smarttop settings, MX51EVK settings and certainly don't
correspond to any shipped or development version of U-Boot that Genesi has ever
had on any Smartbook.

Smartbook since retail production. Remove those few settings that just set the
POR defaults which have already been confirmed for the previous Smarttop DCD
change.

One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks
will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks
