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 v1: Removed bitfields for specifying the device capabilty and accomodate controller revision in compatible field. arch/arm/boot/dts/da850-evm.dts | 7 +++++++ arch/arm/boot/dts/da850.dtsi | 14 ++++++++++++++ 2 files changed, 21 insertions(+), 0 deletions(-)
