rtc: armada38x: reset after rtc power loss
When the RTC block looses power it needs a reset sequence to make it
usable again. Otherwise, writes to the time register have no effect.
This reset sequence combines information from the mvebu_rtc driver in
the Marvell provided U-Boot, and the SolidRun provided U-Boot repo.
Tested on the Armada 388 based SolidRun Clearfog Base.
