In preparation for nulldrv display modes support.
-- v6: win32u: Move display placement logic out of graphics drivers. win32u: Move full display mode lookup out of graphics drivers. win32u: Use current mode position if desired mode doesn't specify it. win32u: Always copy devmode in validate_display_settings. win32u: Read registry or current mode when validation needs it.

This call to find_display_mode() is new. What's the purpose of this call here? I assume you did it to verify the display mode from the registry is valid. In that case, you should call it only for registry modes. The copying of dmDriverExtra also seems redundant now that you always call get_full_mode() in the driver backends.

I think you're trying to find full mode here so that there is less work in the driver, right? If that's the case, you didn't do the copying.

Yes, it was done to make the `get_full_mode` unnecessary in the drivers if the driver extra data is portable. I think we should aim for that if possible, though I don't know how to solve it for xf86vm backend.
