AM62D-EVM evaluation module (EVM) is a low-cost expandable platform board
designed for AM62D2 SoC from TI. It supports the following interfaces:

* 4 GB LPDDR4 RAM
* x2 Gigabit Ethernet expansion connectors
* x4 3.5mm TRS Audio Jack Line In
* x4 3.5mm TRS Audio Jack Line Out
* x2 Audio expansion connectors
* x1 Type-A USB 2.0, x1 Type-C dual-role device (DRD) USB 2.0
* x1 UHS-1 capable micro SD card slot
* 32 GB eMMC Flash
* 512 Mb OSPI NOR flash
* x4 UARTs via USB 2.0-B
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs

Although AM62D2 and AM62A7 differ in peripheral capabilities example
multimedia, VPAC, and display subsystems, the core architecture remains
same. To reduce duplication, AM62D support reuses the AM62A dtsi and the
necessary overrides will be handled in SOC specific dtsi file and a
board specific dts.

Add basic support for AM62D2-EVM.
