sound updates for 4.8

Majority of this update is about ASoC, including a few new drivers,
and the rest are mostly minor changes.  The only substantial change in
ALSA core is about the additional error handling in the
compress-offload API.  Below are highlights:

- Add the error propagating support in compress-offload API

- HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
  default mixer setup change ot turn off the loopback

- Lots of updates for ASoC Intel drivers, mostly board support and bug
  fixing, and to the NAU8825 driver

- Work on generalizing bits of simple-card to allow more code sharing
  with the Renesas rsrc-card (which can't use simple-card due to DPCM)

- Removal of the Odroid X2 driver due to replacement with simple-card

- Support for several new Mediatek platforms and associated boards

- New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
  Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
  Realtek RT5514 and Wolfson WM8758

- more engine code unification (Tvrtko)
- reorganize rps&rc6 setup (Chris Wilson)
- hotplug polling when in deep rpm states, especially fixes vls (Lyude)
- mocs fix for bxt (Imre)
- convert i915 request to use dma fences (Chris)
- prep work for lockless i915 requests/fences (needed for full sync integration)
  from Chris Wilson
- wait for external rendering/fences attached to dma_bufs (Chris)
- tons of small bugfixes all over

Linux 4.7

sound fixes #2 for 4.7-final

Now one more regression fix in addition to the previous pull request:
two changes in the core part are for unusual error paths, while the
rest are the regular HD-audio fixes and one USB-audio regression fix.

sound fixes for 4.7-final

No surprise, just a few small fixes: a couple of changes are seen in
the core part, and both of them are rather for unusual error paths.
The rest are the usual HD-audio fixes.

sound fixes for 4.7-rc7

Here are a collection of small fixes: at this time, we've got a
slightly high amount, but all small and trivial fixes, and nothing
scary can be seen there.

Linux 4.7-rc6

Linux 4.7-rc5

sound fixes for 4.7-rc5

Again pretty calm weeks: we've had only a few trivial / stable
HD-audio fixes in addition to a possible race fix for snd-dummy
driver spotted by syzkaller.

Linux 4.7-rc3

sound fixes for 4.7-rc3

We have only few, mainly HD-audio device-specific fixes.
Realtek codec driver got a slightly more LOC, but they are all for the
new codec chip, and won't affect others at all.

- some polish for the guc code (Dave Gordon)
- big refactoring of gen9 display clock handling code (Ville)
- refactoring work in the context code (Chris Wilson)
