omap3logic: Return omap3logic boards to OF_PLATDATA in SPL

SPL is just simply too tight and we don't really have any
room to shave off any more functionality, so we need OF_PLATDATA
in SPL.

This patch adds the manual enumeration of serial and MMC while
removing the device tree support in SPL and enabling
SPL_OF_PLATDATA.
