clk: sunxi-ng: sun6i-rtc: Add A523 specifics

Browse source

[ Upstream commit 7aa8781f37 ]

The A523's RTC block is backward compatible with the R329's, but it also
has a calibration function for its internal oscillator, which would
allow it to provide a clock rate closer to the desired 32.768 KHz. This
is useful on the Radxa Cubie A5E, which does not have an external 32.768
KHz crystal.

Add new compatible-specific data for it.
