This patch adds a new generic streaming logic for audio over USB.

It defines a model (snd_usb_endpoint) that handles everything that
is related to an USB endpoint and its streaming. There are functions to
activate and deactivate an endpoint (which call usb_set_interface()),
and to start and stop its URBs. It also has function pointers to be
called when data was received or is about to be sent, and pointer to
a sync slave (another snd_usb_endpoint) that is informed when data has
been received.

A snd_usb_endpoint knows about its state and implements a refcounting,
so only the first user will actually start the URBs and only the last
one to stop it will tear them down again.

With this sort of abstraction, the actual streaming is decoupled from
the pcm handling, which makes the "implicit feedback" mechanisms easy to
implement.

In order to split changes properly, this patch only adds the new
implementation but leaves the old one around, so the the driver doesn't
change its behaviour. The switch to actually use the new code is
submitted separately.

unconnected.

produces no sound, even with the mixer input labelled "CD" enabled, and
the volume control in the CD drive set to maximum. This indicates the

The ASoC core currently defaults to using STANDBY rather than OFF for
idle ASoC platform devices, which causes a permanent pm_runtime_get() on
them. This keeps the device active unnecessarily. This can be especially
problematic when the ASoC platform device and DAI device are the same
device.

The distinction between OFF and STANDBY is likely not relevant for ASoC
platform drivers, since they aren't analog devices. So, solve this issue
by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this
turns out to be a problem, this value could be sourced from the
snd_soc_platform_driver, similarly to soc_probe_codec().

Note: Prior to this change, this caused a large (10) runtime_active count
for the Tegra I2S controller even when not in use, and a leak in that
value as streams were started and stopped. This change probably hides a
bug.

Pull virtio S3 support patches from Amit Shah:
 "Turns out S3 is not different from S4 for virtio devices: the device
  is assumed to be reset, so the host and guest state are to be assumed
  to be out of sync upon resume.  We handle the S4 case with exactly the
  same scenario, so just point the suspend/resume routines to the
  freeze/restore ones.

  Once that is done, we also use the PM API's macro to initialise the
  sleep functions.

  A couple of cleanups are included: there's no need for special thaw
  processing in the balloon driver, so that's addressed in patches 1 and
  2.

  Testing: both S3 and S4 support have been tested using these patches
  using a similar method used earlier during S4 patch development: a
  guest is started with virtio-blk as the only disk, a virtio network
  card, a virtio-serial port and a virtio balloon device.  Ping from
  guest to host, dd /dev/zero to a file on the disk, and IO from the
  host on the virtio-serial port, all at once, while exercising S4 and
  S3 (separately) were tested.  They all continue to work fine after
  resume.  virtio balloon values too were tested by inflating and
  deflating the balloon."

Pulling from Amit, since Rusty is off getting married (and presumably
shaving people).
