[PATCH 1/8] ARM: dts: imx7d: cl-som-imx7: add basic module support

[Ilya Ledvich]

CL-SOM-iMX7 is a miniature System-on-Module (SoM) based on
Freescale i.MX7 System-on-Chip family.

http://www.compulab.co.il/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/

Add basic DT support for standalone module (without a carrier board):

* Memory configuration
* I2C2 bus
* PMIC
* UART1
