As of commit 69497eb9 ("drm: bridge: dw-hdmi: Implement DRM
bridge registration") you don't need to use component API, you
can just use a platform driver wrapper.

I guess you want to have support for ADV7511 and dw-hdmi, right?
For component API you need to have a master device which binds
all the components and inits them, for regular API not. I don't
see a clean way to do this (but I'm not that experienced in
component API). Do you need runtime support for both of bridges?
