drm/mcde: Do not use dirty GEM FB handling
This driver has no way to handle damage, the reason the drm_gem_fb_create_with_dirty() was used was because I had the ambition that the driver would only send out updates to DSI command displays whenever something changed, so as to minimize traffic. It turns out this ambition with command mode isn't working in practice because all the MCDE does is to create a continuous stream of DSI commands and while it is possible to send single frame updates with it, it's not been worthwhile. So we are just setting up continuous updates.
