Noralf Trønnes 41b676e03f drm/cma-helper: Add drm_fb_cma_fbdev_init/fini()
Add functions drm_fb_cma_fbdev_init(), drm_fb_cma_fbdev_fini() and
drm_fb_cma_fbdev_init_with_funcs(). These functions relies on the fact
that the drm_fb_helper struct is stored in dev->drm_fb_helper_private
so drivers don't need to store it.
