Make sti driver use register callback to move debugfs
initialization out of sub-components creation.
This will allow to convert driver .load() to
drm_dev_alloc() and drm_dev_register().
sti_compositor bring up 2 crtc but only one debugfs init is
needed so use drm_crtc_index to do it on the first one.
This can't be done in sti_drv because only sti_compositor have
access to the devices.
It is almost the same for sti_encoder which handle multiple
encoder while one only debugfs entry is needed so add a boolean
to avoid multiple debugfs initialization

Commit 8a2fa38fdd removed the mode_fixup because it was empty,
but 652353e6e5 modified it to call drm_mode_set_crtcinfo()
instead.
Both commits are correct, but the merge of the two kept the nonempty
version without the reference to it, as shown by the gcc warning:
drm/sti/sti_crtc.c:54:13: error: 'sti_crtc_mode_fixup' defined but not used
This restores the callback pointer to fix the merge.

Here are sti patches for drm-next.
It brings:
- The support of the atomic_check for the planes and minor fixes for
planes
- The support of the vendor specific infoframe for HDMI and the
support of 2 HDMI properties related to the connector
- The support of the DVO solving panel detection issue and timing issue.
- The support of debugfs for connectors, encoders, crtcs and planes.

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.
I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

A negative pipe causes a special case to be triggered for drivers that
don't have proper VBLANK support. STi does support VBLANKs, so there is
no need for the fallback code.

This serie of patches fix minor bugs around how driver sub-components are
bind and planes z-ordering.
The main part is about atomic support: using more atomic helpers allow us
to simplify the code (~300 lines removed) and to ahve a better match between
drm concepts (planes and crtc) and hardware split.
[airlied: fixed up conflict in atomic code]
* 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjamin.gaignard/kernel:
drm/sti: atomic crtc/plane update
drm/sti: rename files and functions
drm/sti: code clean up
drm/sti: fix dynamic z-ordering
drm: sti: fix sub-components bind
Better fit STI hardware structure.
Planes are no more responsible of updating mixer information such
as z-order and status. It is now up to the CRTC atomic flush to
do it. Plane actions (enable or disable) are performed atomically.
Disabling of a plane is synchronize with the vsync event.
