[PATCH 1/2] misc: eeprom: sunxi: Add new compatibles

[Maxime Ripard]

The Allwinner A10 compatibles were following a slightly different compatible
patterns than the rest of the SoCs for historical reasons. Add compatibles
matching the other pattern to the SID driver for consistency, and keep the
older one for backward compatibility.

 Required properties:
-- compatible: "allwinner,sun4i-sid" or "allwinner,sun7i-a20-sid".
+- compatible: "allwinner,sun4i-a10-sid" or "allwinner,sun7i-a20-sid"
+              (Deprecated: "allwinner,sun4i-sid").
 - reg: Should contain registers location and length
 
 Example for sun4i:
 	sid at 01c23800 {
-		compatible = "allwinner,sun4i-sid";
+		compatible = "allwinner,sun4i-a10-sid";
 		reg = <0x01c23800 0x10>
