[PATCH v2 1/3] arm: dts: armada-38x-solidrun-microsom: configure i2c0 bus

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.
