watchdog: sunxi: add A523 support
The Allwinner A523 SoC moved the watchdog into a separate MMIO frame,
and also shifted the registers a bit: the control, config, and mode
register are located four bytes earlier.
Add the new compatible string, and connect it to the new struct
describing the new register layout.
