arm64: dts: ti: k3-am69-aquila: add dev carrier board peripherals

This change adds support to the below-listed peripherals on Aquila
development carrier board.
 - ETH_2 and related RGMII PHY on the carrier board
 - I2C devices such as EEPROM, Fan-controller, hwmon-INA226A and
   Temperature Sensor
 - OSPI flash memory
