ARM: dts: DRA7: Add the dts files for dra7 SoC and dra7-evm board
Add minimal device tree source needed for DRA7 based SoCs. Also add a board dts file for the dra7-evm (based on dra752) which contains 1.5G of memory with 1G interleaved and 512MB non-interleaved. Also added in the board file are pin configuration details for i2c, mcspi and uart devices on board.
