The DMIC DAI driver specifies a number of 1 to 8 channels for each DAI.
The actual number of mics can currently not be configured in the device
tree or audio glue, but is derived from the min/max channels of the CPU
and codec DAI. A typical CPU DAI has two or more channels, in consequence
a single mic is treated as a stereo/multi channel device, even though
only one channel carries audio data.
This change adds the option to specify the number of used DMIC channels
in the device tree. When specified this value overwrites the default
channels_max value of 8 in the snd_soc_dai_driver struct of the codec.

This patch fixes a number of issues:
1. IOSF_MBI is only needed for byt-cr detection, which is only supported
on Baytrail/Cherrytrail, move to HiFi2 config
2. SND_SOC_INTEL_SST should not select SND_SOC_INTEL_SST_ACPI, the latter
config is only valid for Haswell/Baytrail legacy but not needed by Skylake
3. SND_SST_IPC_ACPI, used only by the atom/sst driver, should not select
SND_SOC_INTEL_SST, none of the code under common/sst*.c is used
This nesting of configs really makes no sense, it's easier to maintain
if for each platform one can control what is strictly required.
Compiled-tested with each of Haswell, Baytrail legacy, HiFi2, SKL cases
selected independently. 0-day and explicit randconfig tests did not report
additional issues and no functionality loss was observed in Intel tests on
HIFI2 and SKYLAKE platforms

PCI/ACPI selections should not happen in Kconfig for machine drivers,

Add distinction between PCI and ACPI HiFi2 platforms and help text.
There should be no functionality change.
The PCI-based platforms may be removed at some point since Medfield
is not really supported by anyone, and with Edison now defunct support for
Merrifield/Edison is to be determined.
The dependency on SND_DMA_SGBUF for Haswell is not clear at this
point and may have to be further updated.

Follow network example suggested by Linus, move Intel definitions
in if/endif block and clarify in help text which options distro
configurations should enable - everything except legacy Baytrail stuff and
NOCODEC (test only)
To avoid user confusion, machine drivers are handled with a submenu made
dependent on this top-level selector.
There should be no functionality change - except that sound capabilities
are restored when using older configs without any user selection.
Note that the SND_SOC_ACPI_INTEL_MATCH config is currently filtered
out by the top-level selector. This will change in the near future to
allow for this option to be selected by both SST and SOF drivers
(simplification with submenu for machine drivers by Vinod Koul)

When restoring registers during runtime resume, we must not write to
I2S_TXDR which is the transmit FIFO as this queues up a sample to be
output and pushes all of the output channels down by one.
This can be demonstrated with the speaker-test utility:
for i in a b c; do speaker-test -c 2 -s 1; done
which should play a test through the left speaker three times but if the
I2S hardware starts runtime suspended the first sample will be played
through the right speaker.
Fix this by marking I2S_TXDR as volatile (which also requires marking it
as readble, even though it technically isn't). This seems to be the
most robust fix, the alternative of giving I2S_TXDR a default value is
more fragile since it does not prevent regcache writing to the register
in all circumstances.
While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these
are not writable so they do not suffer from the same problem as I2S_TXDR
but reading from I2S_RXDR does suffer from a similar problem.

PCM OSS read/write loops keep taking the mutex lock for the whole
read/write, and this might take very long when the exceptionally high
amount of data is given. Also, since it invokes with mutex_lock(),
the concurrent read/write becomes unbreakable.
This patch tries to address these issues by replacing mutex_lock()
with mutex_lock_interruptible(), and also splits / re-takes the lock
at each read/write period chunk, so that it can switch the context
more finely if requested.

The loops for read and write in PCM OSS emulation have no proper check
of pending signals, and they keep processing even after user tries to
break. This results in a very long delay, often seen as RCU stall
when a huge unprocessed bytes remain queued. The bug could be easily
triggered by syzkaller.
As a simple workaround, this patch adds the proper check of pending
signals and aborts the loop appropriately.
