This fails to build when CONFIG_DA850_UI_SD_VIDEO_PORT is switched off.
Probably means you need separate functions for registering capture and
display parts.

I haven't reviewed rest of the patchset yet. Just noticed these while
applying them for some testing. You may want to wait sometime before
sending the next version.
