In my opinion we shouldn't add the "depends on OF" since that will
decrease the amount of compile testing. It's somewhat the opposite of
adding "if COMPILE_TEST" to your driver. ;-)

I think we could get rid of one of the "#if" statements in the driver
anyway as of commit c9e358dfc4a8 ("driver-core: remove conditionals
around devicetree pointers") from ~12 years ago. If we did something
similar in "struct drm_bridge" we could drop both #ifs.
