Set ethernet mac address in late init for Tinker Board, prevents getting a random mac address each boot.

Read mac address from eeprom, first 6 bytes from m24c08@50. Same as /etc/init.d/rockchip.sh on Tinker OS.

Changes in v3: - Add i2c_eeprom_{read,write} functions - Use uclass_first_device_err() to find eeprom - Use i2c_eeprom_read() to read eeprom

Changes in v2: - Change to use i2c_eeprom device driver
