i2c: Add DT bindings for Xscale I2C masters
This adds a device tree binding for Intel XScale I2C masters. We define compatible strings for the iop3xx and ixp4xx chip families. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

+i2c Controller on XScale platforms such as IOP3xx and IXP4xx
+
+Required properties:
+- compatible : Must be one of
+ "intel,iop3xx-i2c"
+ "intel,ixp4xx-i2c";
+- reg
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+- Child nodes conforming to i2c bus binding

+Example:

+ compatible = "intel,ixp4xx-i2c";
+ reg = <0xc8011000 0x18>;
+ interrupts = <33 IRQ_TYPE_LEVEL_LOW>;
