Subject: [PATCH v4 4/5] 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.

Since v2:
Remove properties specifying for highspeed card capability.
Since v1:
Removed bitfields for specifying the device capabilty and accomodate
controller revision in compatible field.
