SolidRun Armada-388 SoM has an i2c bus supporting on-som eeprom, and
peripherals on a carrier.
armada-38x.dtsi disables this bus by default, it should be enabled by
som or carrier dts.
Linux has moved i2c0 from helios-4 board dts to som dtsi, including
status, pinctrl and clock speed.
Copy these settings from mainline.
This fixes accessing i2c bus from u-boot commandline.

Applied to u-boot-marvell/master
Thanks,
