dm: rtc: Add a uclass for real-time clocks
Add a uclass for real-time clocks which support getting the current time, setting it and resetting the chip to a known-working state. Some RTCs have additional registers which can be used to store settings, so also provide an interface to these. Signed-off-by: Simon Glass <>

+ Enable drver model for real-time-clock drivers. The RTC uclass
