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).

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

Add the obvious compatible name to the existing I2C binding, and pair
it with the existing A31 fallback compatible string, as the devices
are compatible.
On the way use enums to group all compatible devices together.

Some binding that were introduced early on got a comment to enable
additionalProperties, but we couldn't due to the generic properties being
reported as errors.
The way we're dealing with this now is to use the draft-08's
unevaluatedProperties (even though the tools doesn't do anything with it
yet).
Let's convert those old bindings to it.

One example has a compatible that isn't a valid combination according to
the binding, and now that the examples are validated as well, this
generates a warning.
Let's fix this.
