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.
