[PATCH 1/4] dt-bindings: net: can: Add support for Allwinner D1 CAN controller

[Jookia]

From: John Watts <contact at jookia.org>

The Allwinner D1 has two CAN controllers, both a variant of the R40
controller. Unfortunately the registers for the D1 controllers are
moved around enough to be incompatible and require a new compatible.

Introduce the "allwinner,sun20i-d1-can" compatible to support this.
