Subject: [PATCH RESEND v2 1/2] drm/sun4i: sun4i: Register quirks with the backend structure

In prevision for introducing a new quirk that will be used at atomic
plane check time, register the quirks structure with the backend
structure. This way, it can easily be grabbed where needed.

Version 2 of this series was resent to include this patch, that was
missing from the original v2 submission but is still very much needed.
