hw/arm/allwinner: add RTC device support
Allwinner System-on-Chips usually contain a Real Time Clock (RTC)
for non-volatile system date and time keeping. This commit adds a generic
Allwinner RTC device that supports the RTC devices found in Allwinner SoC
family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc).
The following RTC functionality and features are implemented:
* Year-Month-Day read/write
* Hour-Minute-Second read/write
* General Purpose storage
The following boards are extended with the RTC device:
* Cubieboard (hw/arm/cubieboard.c)
* Orange Pi PC (hw/arm/orangepi.c)
