drm/meson: Don't remove bridges which are created by other drivers
Stop calling drm_bridge_remove() for bridges allocated/managed by other
drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}.
drm_bridge_remove() unregisters the bridge so it cannot be used
anymore. Doing so for bridges we don't own can lead to the video
pipeline not being able to come up after -EPROBE_DEFER of the VPU
because we're unregistering a bridge that's managed by another driver.
The other driver doesn't know that we have unregistered it's bridge
and on subsequent .probe() we're not able to find those bridges anymore
(since nobody re-creates them).
This fixes probe errors on Meson8b boards with the CVBS outputs enabled.
Fixes: 09847723c12f ("drm/meson: remove drm bridges at aggregate driver unbind time")
Fixes: 42dcf15f901c ("drm/meson: add DSI encoder")
