Add basic support for SBC-T43: a CM-T43 based single board computer.
CM-T43 is an AM437x based System-on-Module designed to serve as a building
block in embedded applications. SBC-T43 is composed of CM-T43 module on
top of the SB-SOM-T43 baseboard.
Basic support includes UART, GPIO, and I2C.

Add PMIC support for CompuLab cm-t43 module. For now we keep all regulators
enabled until this could be refined with power management support.

One of the CompuLab cm-t43 configurations comes with on-board NAND flash as
primary storage. It is partitioned into kernel, dtb, and rootfs partitions.
Add it to the device tree.

CM-T43 comes with 2 ethernet ports connected to the cpsw subsystem, which
has 2 modes of operation: switch mode and dual emac mode.
Add the relevant muxing and set it up to work in dual emac mode by
default.

CompuLab SB-SOM baseboard is a carrier board for multiple arm-based SoMs.
It currently supports (with minor adjustments to assembly) CM-T43, CM-T54,
and CM-QS600 modules. It is a building block in the SBC-T43 single board
computer, which consists of cm-t43 on top of sb-som-t43.
