ARM: dts: am57xx: cl-som-am57x: add basic module support 

Add support for CompuLab CM-SOM-AM57X board.

CL-SOM-AM57x is a miniature System-on-Module (SoM) based on
TI Sitara AM57x ARM Cortex-A15 System-on-Chip family.

https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/

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

* Memory configuration
* Heartbeat led
* I2C1 and I2C4
* PMIC
* SATA
