drm: remove drmP.h from drm_modeset_helper.h

With the removal of drmP.h from drm_modeset_helper.h
the drmP.h are no longer included by any include files
in include/drm.
The drmP.h file is thus only included explicit
either in .c files or in local .h files.
This makes the process of deleting the drmP.h includes easier
as we have a more local dependency chain.

v2:
- moved updates of .c files in drm/ to a dedicated
patch. This allows the updates to the *.c files
to be committed without the removal part.
So this patch can wait if it causes build failures
due to pending changes

drm/modeset-helper: Add simple modeset suspend/resume helpers

Add drm_mode_config_helper_suspend/resume() which takes care of
atomic modeset suspend/resume for simple use cases.
The suspend state is stored in struct drm_mode_config.

drm: Pass 'dev' to drm_helper_mode_fill_fb_struct()

Pass the drm_device to drm_helper_mode_fill_fb_struct() so that we can
populate fb->dev early. Will make it easier to use the fb before we
register it.

drm/kms-helpers: Extract drm_modeset_helper.[hc]

While reviewing docs I spotted that we have a few functions that
really just don't fit into their containing helper library section.
Extract them and shovel them all into a new library for random one-off
aux stuff.

v2: Remove wrongly added files for real.
