Subject: [PATCH 1/3] ARM: dts: keystone-k2g: Add device state controller node

Add the device state controller node as a syscon node to the
Keystone 2 Galileo SoC. This module provides similar device
control functionality as that on the existing K2 SoCs.

One example usage would be the boot address programming of the
DSP processor sub-system.
