[0/3] drm/bridge: Create a function to abstract panels away

Hi,

This series used to be part of the DSI probe order series, but got removed
since it wasn't useful there anymore.

However, I still believe there is value in moving towards merging bridges and
panels by only making encoder (or upstream bridges) manipulate bridges.

The first patch creates a new helper that does just this by looking for a
bridge and a panel, and if a panel is found create a panel_bridge to return
that bridge instead.

The next two patches convert the vc4 encoders to use it.

If it's accepted, I plan on converting all the relevant users over time.

Let me know what you think,
Maxime
