Subject: [PATCH] drm/sun4i: Add missing frontend compatibles for A10, A13, A20 and A31

Although frontend nodes are defined in the device-trees of the
aforementioned platforms, there are no matching compatibles defined in
the driver. This makes it impossible to probe the frontend on these
platforms.

Adding the appropriate compatibles to the driver fixes the issue.
