Subject: [PATCH 04/12] rtc: sun6i: add support for R329 RTC

From: Icenowy Zheng <icenowy@...c.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.
