The MIPI DBI standard support more pixel formats than what this helper supports. Add an init function that lets the driver use different format(s). This avoids open coding mipi_dbi_init() in st7586. 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.
