[PATCH 1/2] i2c: sunxi: Add new i2c compatibles

[Maxime Ripard]

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the i2c driver for consistency, and keep the
older one for backward compatibility.
