ARM: dts: Fix I2C repeated start issue on Armada-38x
All the Armada 38x(380, 385, 388) have a silicon issue in the I2C controller which violates the I2C repeated start timing (errata FE-8471889). i2c-mv64xxx driver handles this errata based on the compatible string "marvell,mv78230-a0-i2c". This patch activates the "marvell,mv78230-a0-i2c" compatible string for the I2C controller on armada-38x SoC based devices.
