From: R Sricharan <r.sricha...@ti.com>

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.

ref: [1], we discussed that we should now be able to introduce all instances of h/w blocks into the dra7.dts.
