[RFC PATCH 06/12] dt-bindings: rtc: sun6i: add compatible string for V831/V833 RTC

[Icenowy Zheng]

V831/V833 SoCs (the same die) have a RTC block similar to the one in H6,
but allow to generate the osc32k clock from osc24M.

Add a new compatible string for that.

The functionality of dividing osc24M to generate osc32k is still TODO.
