[RESEND PATCH] rtc: sun6i: add support for R329 RTC

[Samuel Holland]

From: Icenowy Zheng <icenowy@aosc.io>

Allwinner R329 has a RTC with a similar time storage with H616 but a
slightly different clock part.

As we have already handled the R329 RTC clocks in the CCU driver, add a
compatible string to RTC driver to allow probing of the RTC.

Resending this patch separately from Icenowy's R329 series[1] because it
is also needed for D1 (which has R329 as its fallback compatible[2]), so
I would like to get it in to 5.20.

Thanks!

BTW when will you put D1 DTs into kernel?

I am preparing a series for the stacked interrupt controller at the moment.
After I send that, I will send an initial devicetree series, hopefully by the
end of the weekend.

Samuel
