mx6sx: udoo_neo: Enable distro boot options in config

The include/configs/udoo_neo.h already includes the distro defaults
include files so it seems the board was missed in the move to the
config file, whether that in initial commit or conversion, so
enable the option now and remove duplicated settings.
