This patch changes the function pointers in 'dss_mgr_ops' to get 'enum

In order to remove uses of 'struct omap_overlay_manager' we need to get
rid of using omapdss_find_mgr_from_display() when initializing omapdrm.
Instead of using omapdss_find_mgr_from_display() and mgr->id to find the
dispc channel used for the given display, we can instead use
omapdss_find_output_from_display(), and get the output->dispc_channel
from there.
We can also remove omapdss_find_mgr_from_display() as it's no longer
used.

omapdrm and omapfb still share the same include/video/omapdss.h. We need
to change that so that we can proceed with omapdrm work.
However, it's not trivial to make separate omapfb and omapdrm versions
of omapdss.h, as that file is also included in other places like arch
code, audio code and omap_vout code. So we'll do it piece by piece.
This patch makes private versions of all the dispc function declarations
that are in omapdss.h. For omapdrm we create a new file,
drivers/gpu/drm/omapdrm/dss/omapdss.h, which will contain headers meant
to be visible outside omapdss.

For legacy reasons omapdss handles system suspend/resume via PM notifier
callback, where the driver disables/resumes all the outputs.
This doesn't work well with omapdrm. What happens on suspend is that the
omapdss disables the displays while omapdrm is still happily continuing
its work, possibly waiting for an vsync irq, which will never come if
the display output is disabled, leading to timeouts and errors sent to
userspace.
This patch moves the suspend/resume handling to omapdrm, and the
suspend/resume is now done safely inside modeset lock.

On OMAP4 and OMAP5 ES1.0 the HDMI_WP_VIDEO_TIMING_H:HSW field is
set directly to the HSW value. On later SoCs the field needs to be
programmed with the value of HSW-1.
Currently the driver always programs the field with the HSW value. Most
videomodes seem to work fine with that, but at least low resolution
interlaced modes don't work at all.
This patch fixes the HSW for OMAP5 ES2.0+ SoCs.

We occasionally see DISPC sync-lost errors when enabling and disabling
HDMI. Sometimes we get only a few, which get handled (ignored) by the
driver, but sometimes there's a flood of the errors which doesn't seem
to stop.
The HW team has root caused this to the order in which HDMI and DISPC
are enabled/disabled. Currently we enable HDMI first, and then DISPC,
and vice versa when disabling. HW team's suggestion is to do it the
other way around.
This patch changes the order, but this has two side effects as the pixel
clock is produced by HDMI, and the clock is not running when we
enable/disable DISPC:
* When enabling DISPC first, we don't get vertical sync events
* When disabling DISPC last, we don't get FRAMEDONE event
At the moment we use both of those to verify that DISPC has been
enabled/disabled properly. Thus this patch also needs to change the
omapdrm and omapdss which handle the DISPC side.

The short version:
omapfb and omapdrm have shared low level drivers (omapdss and panel drivers),
making further development of omapdrm difficult. After these patches omapfb and
omapdrm have their own versions of the drivers, which are more or less
direct copies for now but will diverge soon.
This also means that omapfb (everything under drivers/video/fbdev/omap2/) is
now in maintenance mode, and all new development will be done for omapdrm
(drivers/gpu/drm/omapdrm/).
