Simon Glass dbeda5b225 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.
