defining CONFIG_OF_BOARD_SETUP should be independent of defining
CONFIG_VIDEO or CONFIG_VIDEO_DT_SIMPLEFB. DT fixup by board setup
code is often done i.e. for auto-detected memory size, adjusting
different node properties or adding/deleting whole nodes. If
someone defines CONFIG_OF_BOARD_SETUP for these purposes and also
defines CONFIG_VIDEO_DT_SIMPLEFB, the "already defined" warnings
will appear. This can be left as is for now, but should be addressed
in the long term.
