[PATCH 3/4] can: sun4i_can: Add send support for the Allwinner D1

[Jookia]

From: John Watts <contact at jookia.org>

The controllers present in the D1 are extremely similar to the R40
and require the same reset quirks. This alone can support sending
packets. An extra quirk is needed to support receiving packets.
