Back-merge to the development branch for further fixes of sequencer
stuff.

The capture interface does not work, and the playback interface
actually supports only 48kHz unlike what is advertised (44.1, 32, 22,
16, 8).
The only unknown here is if there are other devices that use the same
product ID, but given that this ID is currently unknown, I would assume
it is specially allocated for the nura headset.

ASoC: Updates for v4.16
Some more updates for v4.16, the big things here are the ST DFSDM driver
and the IIO patches required to support that and even more in the
neverending series of code quality improvements for x86, including
Pierre's work to improve the Kconfig. The unused SN95031 driver and
associated board support are also removed, they haven't been buildable
for a considerable time without anyone noticing.

Commit 78f5605c0329 ("ASoC: rt5645: cleanup DMI matching code") did a
lot of useful cleanups. This patch adds a default case to enable
jack detection if there is no pdata, device property or quirk.
The chosen jd-mode3 is the most common and should limit the addition
of new DMI-based quirks. Existing DMI quirks which only set this mode
are left as is and not removed.

The ALSA sequencer ioctls have no protection against racy calls while
the concurrent operations may lead to interfere with each other. As
reported recently, for example, the concurrent calls of setting client
pool with a combination of write calls may lead to either the
unkillable dead-lock or UAF.
As a slightly big hammer solution, this patch introduces the mutex to
make each ioctl exclusive. Although this may reduce performance via
parallel ioctl calls, usually it's not demanded for sequencer usages,
hence it should be negligible.

In case of error, the function devm_iio_device_alloc() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

The new stm32_adfsdm driver has incomplete dependencies as shown
by Kconfig:
warning: (SND_SOC_STM32_DFSDM && LMP91000) selects IIO_BUFFER_CB which has unmet direct dependencies (IIO && IIO_BUFFER)
sound/soc/stm/stm32_adfsdm.o: In function `stm32_adfsdm_trigger':
stm32_adfsdm.c:(.text+0x8c): undefined reference to `stm32_dfsdm_get_buff_cb'
stm32_adfsdm.c:(.text+0x9c): undefined reference to `stm32_dfsdm_release_buff_cb'
This makes the dependency on SND_SOC_STM32_DFSDM unconditional, so we can
always resolve the stm32_dfsdm_get_buff_cb/stm32_dfsdm_release_buff_cb
symbols and get the implied IIO_BUFFER dependency.
compile-testing on other platforms is still possible as long as that IIO
driver is there.

muldiv32() contains a snd_BUG_ON() (which is morphed as WARN_ON() with
debug option) for checking the case of 0 / 0. This would be helpful
if this happens only as a logical error; however, since the hw refine
is performed with any data set provided by user, the inconsistent
values that can trigger such a condition might be passed easily.
Actually, syzbot caught this by passing some zero'ed old hw_params
ioctl.
So, having snd_BUG_ON() there is simply superfluous and rather
harmful to give unnecessary confusions. Let's get rid of it.

This adds MODULE_LICENSE/AUTHOR/DESCRIPTION tags to the ux500
platform drivers, to avoid these build warnings:

WARNING: modpost: missing MODULE_LICENSE() in sound/soc/ux500/snd-soc-ux500-mach-mop500.o
The company no longer exists, so the email addresses of the authors
don't work any more, but I've added them anyway for consistency.
