Subject: [PATCH] wdt: sunxi: Introduce a new compatible for the A10 and A31

For historical reasons, the Allwinner A10 compatibles are not following the
patterns used for this other Allwinner SoCs.

Introduce a new compatible following the usual pattern, and deprecate the olders.

 Required properties:
 
-- compatible : should be "allwinner,<soc-family>-wdt", the currently supported
-  SoC families being sun4i and sun6i
+- compatible : should be either "allwinner,sun4i-a10-wdt" or

 - reg : Specifies base physical address and size of the registers.
 
 Example:
