At present there are only 8-bit and 32-bit read/write routines in
the rtc uclass driver. This adds the 16-bit support.

The current check is incorrect and will fail when any non-zero byte is read.
Fix it.

dm: rtc: Add a uclass for real-time clocks2015-05-06T02:58:39ZSimon Glasssjg@chromium.org2015-04-20T18:37:23Zurn:sha1:dbeda5b2255089889788e0dd3478680feec86139
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.
