The I2C controller IP used in the Allwinner A523/T527 SoCs is compatible with the ones used in the other recent Allwinner SoCs. Add the A523 specific compatible string to the list of existing names falling back to the allwinner,sun8i-v536-i2c string.

Only use "marvell,mv78230-a0-i2c" for a very rare, initial

version of the SoC which had broken offload support. Linux

auto-detects this and sets it appropriately.
