[PATCH v2 04/14] dt-bindings: rtc: sun6i-rtc: Export internal RC oscillator

[Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>]

Experiments showed that on at least the H3/H5/A64 the RTC's internal
oscillator also feeds the CPUS mux in the PRCM.

Export this clock through the device tree, instead of having to use
a dummy fixed-clock device node, for the PRCM to consume. This will
properly describe the relationship between the clocks.
