The RTC in the JZ4770 is compatible with the JZ4760, but has an extra
register that permits to configure the behaviour of the CLK32K pin. The
same goes for the RTC in the JZ4780.
Therefore, the ingenic,jz4770-rtc and ingenic,jz4780-rtc strings do not
fall back anymore to ingenic,jz4760-rtc. The ingenic,jz4780-rtc string
now falls back to the ingenic,jz4770-rtc string.
Additionally, since the RTCs in the JZ4770 and JZ4780 support outputting
the input oscillator's clock to the CLK32K pin, the RTC node is now also
a clock provider on these SoCs, so a #clock-cells property is added.
