video: Update video_set_default_colors() to support invert
It is useful to be able to invert the colours in some cases so that the text matches the background colour. Add a parameter to the function to support this. It is strange that function takes a private data structure from another driver as an argument. It seems better to pass the device and have the function internally work out how to find its required information. Signed-off-by: Simon Glass <sjg@chromium.org>
