ARM: dts: dra7-evm: add pinmux configuration for mmc1/2
Add pinmux configuration for SD card slot and eMMC device found on TI's DRA74x EVM. Only the default modes are supported. For higher speed modes (UHS and HS200) to function, we need full fledged IODelay support in kernel. IODelay support is yet to be added.
