The suspend_late handler saves some registers and powers off the device,
so it doesn't have a big overhead. Calling it at S4 poweroff_late time
makes the power off handling identical to the S3 suspend and S4 freeze

To avoid processing hotplug events we disable connector polling for the
duration of S3 suspend. We also disable it for S4 freeze, and keep it
disabled after S4 thaw. This won't prevent though hotplug processing,
since we re-enable interrupts anyway. There is also no need to prevent
it at that time, since we reinitialize everything during thaw, so the
device is in a consistent state. So to simplify things enable polling
during thaw, which will allow us to handle S4 thaw the same way as S3
resume in an upcoming patch.

The logic to skip restoring GTT mappings was added to speed up
suspend/resume, but not on old GENs where not restoring them caused
problems. The check for old GENs is based on the existence of OpRegion,
but this doesn't work since opregion is initialized only after
the check. So we end up always restoring the mappings.
On my BYT - which has OpRegion - skipping restoring the mappings during
suspend doesn't work, I get a GPU hang after resume. Also the logic of
when to allow the optimization during S4 is reversed: we should allow it
during S4 thaw but not during S4 restore, but atm we have it the other
way around in the code.
Since correctness wins over optimal code and since the optimization
wasn't used anyway I decided not to try to fix it at this point, but
just remove it. This allows us to unify the S3 and S4 handlers in the

i915_suspend() is called from the DRM legacy S3 suspend/S4 freeze paths
and the switcheroo suspend path. For switcheroo we only ever need to
perform a full suspend (PM_EVENT_SUSPEND) and for the DRM legacy path
we can handle the S4 freeze (PM_EVENT_FREEZE) the same way as S3
suspend. The only difference atm between suspend and freeze is that
during freeze we don't disable the PCI device, but there is no reason
why we can't do so. So unify the two cases to reduce complexity.
Note that for the DRM legacy case the thaw event is not handled, so
we disable the display before creating the hibernation image and it
won't get re-enabled until reboot. We could fix this leaving the
display enabled for the image creation/writing (if we care enough
about UMS), but this can be done as a follow-up.

"I did some test with bdw:
"The maximum is 128 writes, resulting the 8 bit length
field of the command being 0xff, thus following the spec.
The 128'th write went through.
"Perhaps the max command length is then less in older gens?
"Perhaps WARN_ON(x > 128) in MI_LOAD_REGISTER_IMM would be in place
but one needs minor tweak to command parser a bit also then.
#define I915_MAX_WA_REGS 16

Even if the fb is the same we should still check if the sizes are
valid to be set.

Move check inside intel_crtc_cursor_set_obj() to
intel_check_cursor_plane(), we only use it there so move them out to
make the merge of intel_crtc_cursor_set_obj() into
intel_check_cursor_plane() easier.
This is another step toward the atomic modesetting support and unification
of plane operations such pin/unpin of fb objects on i915.
v2: take Ville's comment: move crtc_{w,h} assignment a bit down in the
code
v3: take Ville's comment: kept only the restructuring changes, the rest of
the code was moved to a separated patch since it is a bug fix (we weren't
checking sizes when the fb was the same)

Now that universal planes are in place we don't need this plane unref on
failures.

Fold intel_pipe_set_base() in the update primary plane path merging
pieces of code that are common to both paths.
Basically the the pin/unpin procedures are the same for both paths
and some checks can also be shared (some of the were moved to the
check() stage)
v2: take Ville's comments:
- remove unnecessary plane check
- move mutex lock to inside the conditional
- make the pin fail message a debug one
- add a fixme for the fastboot hack
- call intel_frontbuffer_flip() after FBC update
v3: take more Ville's comments:
- fold update code under if (intel_crtc->active), and do the
visible/!visible split inside.
- check ret inside the same conditional we assign it
v4: don't use intel_enable_primary_hw_plane(), the primary_enabled
check inside will break page flips
v5: take more Ville's comments:
- set primary_enabled to true and add BDW hack
- unify if (old_fb) and if (old_fb != fb)
v6: take more Ville's comments:
- make was_primary bool and fix its check
- add the BDW vblank wait comment

As stated in the few previous commits, IS_ULT/ULX() is better
per-platform as it has different consequences depending on the platform.
We now can get rid of it.

IS_ULT() wasn't taking into account SKL so we had a warn with SPT-LP.
We don't realy need those checks here, and as we don't need to introduce
IS_SKL_ULT/ULX() at the moment, let's just drop them.
