[PATCH v5 12/20] dt-bindings: rtc: sun6i: Add H616 compatible string

After close lookup I would disagree with this observation. Major difference is 
that H616 doesn't support usage of external 32768 Hz oscillator. It uses 24 
MHz oscillator with divider for that case. Due to that change, whole logic for 
external oscillator should go out. Additionally, this logic overwrites default 
value in LOSC_CTRL register, which is not nice (there is no documentation for 
those bits). 

Best regards,
Jernej
