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:

- SoC families being sun4i and sun6i
+- compatible : should be either "allwinner,sun4i-a10-wdt" or
