The MIPI DBI standard support more pixel formats than what this helper

st7586 sets preferred_depth but this is not necessary since it only
supports one format.
Although that might not always be the case. FYI, we are finding that
having XRGB8888 for a 2bpp grayscale display is not the greatest. When
we want to do direct drawing on the screen, we haven't found very good
support in existing graphics libraries for embedded systems for this
format. If I had more free time, I would like to look at adding
grayscale support to DRM.
