Subject: [PATCH v2 1/2] ARM: dts: sun4i: Add CAN node and can0_pins_a pinctrl settings

The A10 SoC has an on-board CAN controller. This patch adds the device node
and the corresponding pinctrl settings for pins PH20 and PH21.

This patch is adapted from the description in
Documentation/devicetree/bindings/net/can/sun4i_can.txt
