Subject: [PATCH v5 3/4] ARM: davinci: da850: add mmc DT entries

Add DT entry for MMC. Also add entry for pinmux information.
Tested:
1) Without GPIO card detection and EDMA support as DT support for
   GPIO and EDMA are yet come.
2) By creating/deleting files and mounting/unmounting the partition.
