da850/omap-l138: Add support to read u-boot image from MMC/SD
DA850/OMAP-L138 does not support strict MMC/SD boot mode. SPL will be in SPI flash and U-Boot image will be in MMC/SD card. SPL will do the low level initialization and then loads the u-boot image from MMC/SD card. Define CONFIG_SPL_MMC_LOAD macro in the DA850/OMAP-L138 configuration file to enable this feature.
