drm/fb-helper: Remove preferred_bpp parameter from fbdev internals
Store the console's preferred BPP value in struct drm_fb_helper
and remove the respective function parameters from the internal
fbdev code.
The BPP value is only required as a fallback and will now always
be available in the fb-helper instance.
No functional changes.
