dt-bindings: i2c: mv64xxx: Add variants with offload support

V536 and newer Allwinner SoCs contain an updated I2C controller which
includes an offload engine for master mode. The controller retains the
existing register interface, so the A31 compatible still applies.

Add the V536 compatible and use it as a fallback for other SoCs with the
updated hardware. This includes two SoCs that were already documented
(H616 and A100) and two new SoCs (R329 and D1).
