arm64: dts: ti: Add basic support for phyBOARD-Lyra-AM625

The phyCORE-AM62x [1] is a SoM (System on Module) featuring TI's AM62x SoC.
It can be used in combination with different carrier boards.
This module can come with different sizes and models for
DDR, eMMC, SPI NOR Flash and various SoCs from the AM62x family.

A development Kit, called phyBOARD-Lyra [2] is used as a carrier board
reference design around the AM62x SoM.

Supported features:
  * Debug UART
  * SPI NOR Flash
  * eMMC
  * 2x Ethernet
  * Micro SD card
  * I2C EEPROM
  * I2C RTC
  * GPIO Expander
  * LEDs
  * USB
