ARM: dts: AM572x-IDK Initial Support 

The AM572x-IDK board is a board based on TI's AM5728 SOC
which has a dual core 1.5GHz A15 processor. This board is a
development platform for the Industrial market with:
- 2GB of DDR3L
- Dual 1Gbps Ethernet
- HDMI,
- PRU-ICSS
- uSD
- 16GB eMMC
- CAN
- RS-485
- PCIe
- USB3.0
- Video Input Port
- Industrial IO port and expansion connector

The link to the data sheet and TRM can be found here:

http://www.ti.com/product/AM5728



This patch creates a common dtsi file that will provide a common board
dtsi file to define the nodes that are common to AM57xx (including the
upcoming AM5718) IDK boards.

Initial support is only for basic peripherals
