Subject: [PATCH v9 02/11] dt-bindings: rtc: sun6i: Add H616 compatible string

Add the obvious compatible name to the existing RTC binding.
The actual RTC part of the device uses a different day/month/year
storage scheme, so it's not compatible with the previous devices.
Also the clock part is quite different, as there is no external 32K LOSC
oscillator input.
