Since it's 100% dummy, why put LVDS into the name? This little thing here
could be our generic "wrap drm_panel and attach it to a chain" helper. So
what about calling this _The_ drm_panel_bridge, and also linking it into
docs to feature it a bit more prominently.

I came up with this because I spotted some refactoring belows for building
this helper, until I realized that this driver _is_ the helper I think we
want ;-) Only thing missing is an exported function to instantiate a
bridge with just a drm_panel as the parameter. And putting it into the
drm_kms_helper.ko module.

We have piles of this exact dummy callback all over, maybe make it the
default and rip them all out?
