drm/fbdev-dma: Fix documented default preferred_bpp value

As of commit 6c80a93 ("drm/fb-helper: Initialize fb-helper's preferred BPP in prepare function"), the preferred_bpp parameter of drm_fb_helper_prepare() defaults to 32 instead of drm_mode_config.preferred_depth. Hence this also applies to drm_fbdev_dma_setup(), which just passes its own preferred_bpp parameter.
