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

v3:
* Move PMIC to I2C4
* Reformat subject
v2:
* Fixed voltages (for OPP_HIGH) for VDD_GPU, VDD_IVA, VDD_DSPEVE
* Added comments for VDDA_1V8_PHYA/B
* Add "regulator-always-on" property for ldousb_reg
