arm64: dts: ti: Add support for AM62A7-SK 

AM62A StarterKit (SK) board is a low cost, small form factor board
designed for TI’s AM62A7 SoC. It supports the following interfaces:
* 2 GB LPDDR4 RAM
* x1 Gigabit Ethernet interface
* x1 HDMI Port with audio
* x1 Headphone Jack
* x1 USB2.0 Hub with two Type A host and x1 USB Type-C DRP Port
* x1 UHS-1 capable µSD card slot
* M.2 SDIO Wifi + UART slot
* 1Gb OSPI NAND flash
* x4 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin User Expansion Connector
* 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO)
* 20-pin header for Programmable Realtime Unit (PRU) IO pins
* 40-pin CSI header

Add basic support for AM62A7-SK.
