drm/radeon/audio: fix missing multichannel PCM SAD in some cases
The current code writing SADs to the audio registers seems to assume
that there is at most a single SAD per audio format.
However, that is not the case. Especially for PCM it is somewhat common
for sinks to have two SADs, one for 8-channel and one for 2-channel
audio, which may have different supported sample rates (i.e. the sink
supports stereo audio at higher sample rates than multichannel audio).
Because of this, only the 2-channel SAD may be used if it appears before
the 8-channel SAD. Unless other SADs require otherwise, this may cause
the ALSA HDA driver to allow stereo playback only.
Fix the code to pick the PCM SAD with the highest number of channels,
while merging the rate masks of PCM SADs with lower amount of channels
into the additional stereo rate mask byte.
Technically there are even more cases to handle (multiple non-PCM SADs
of the same type, more than two PCM SADs with varying channel counts,
etc), but those have not actually been encountered in the field and
handling them would be non-trivial.

Bit a bit -fixes pull request in the merge window than usual dua to two
feauture-y things:
- Display CRCs are now enabled on all platforms, including the odd DP case
on gm45/vlv. Since this is a testing-only feature it should ever hurt,
but I figured it'll help with regression-testing -fixes. So I left it
in and didn't postpone it to 3.14.
- Display power well refactoring from Imre. Would have caused major pain
conflict with the bdw stage 1 patches if I'd postpone this to -next.
It's only an relatively small interface rework, so shouldn't cause pain.
It's also been in my tree since almost 3 weeks already.
That accounts for about two thirds of the pull, otherwise just bugfixes:
- vlv backlight fix from Jesse/Jani
- vlv vblank timestamp fix from Jesse
- improved edp detection through vbt from Ville (fixes a vlv issue)
- eDP vdd fix from Paulo
- fixes for dvo lvds on i830M
- a few smaller things all over
Note: This contains a backmerge of v3.12. Since the -internal branch
always applied on top of -nightly I need that unified base to merge bdw
patches. So you'll get a conflict with radeon connector props when pulling
this (and nouveau/master will also conflict a bit when Ben doesn't
rebase). The backmerge itself only had conflicts in drm/i915.

drm/nouveau: consider CLASS_DISPLAY_3D devices while detecting dsm/optimus
The present code assumes that optimus is present whenever two

seem to be the case of newer laptops with optimus, in which
case the nvidia gpu is a PCI_CLASS_DISPLAY_3D device.

qxl: add a connector property to denote hotplug should rescan modes.
So GNOME userspace has an issue with when it rescans for modes on hotplug
events, if the monitor has no EDID it assumes that nothing has changed on
EDID as with real hw we'd never have new modes without a new EDID, and they
kind off rely on the behaviour now, however with virtual GPUs we would
like to rescan the modes and get a new preferred mode on hotplug events

guest resizes with it).
