drm/vc4: Recognize a more specific compatible string for V3D.

anholt · anholt · commit 90d7116061f8 · 2016-03-13T18:54:24.000-07:00
The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D.  Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.
