Similar to usbboot, add command line to boot from raw mmc partition using common_diskboot(), which supports legacy or FIT images.
Usage: mmcboot loadAaddr dev:part
Where <loadAddr> defaults to CONFIG_SYS_LOAD_ADDR, and dev:part defaults to ${bootdevice}.
Also fixing config macro usage for CONFIG_SUPPORT_EMMC_BOOT (suggested by checkpatch.pl).
