The Lenovo Yoga 9 14IAP7 is set up similarly to the Thinkpad X1 7th and
8th Gen. It also has the speakers attached to NID 0x14 and the bass
speakers to NID 0x17, but here the codec misreports the NID 0x17 as
unconnected.

The pincfg and hda verbs connect and activate the bass speaker
amplifiers, but the generic driver will connect them to NID 0x06 which
has no volume control. Set connection list/preferred connections is
required to gain volume control.

For avoiding the potential deadlock via kill_fasync() call, use the
new fasync helpers to defer the invocation from the control API.  Note
that it's merely a workaround.

Another note: although we haven't received reports about the deadlock
with the control API, the deadlock is still potentially possible, and
it's better to align the behavior with other core APIs (PCM and
timer); so let's move altogether.

Currently the call of kill_fasync() from an interrupt handler might
lead to potential spin deadlocks, as spotted by syzkaller.
Unfortunately, it's not so trivial to fix this lock chain as it's
involved with the tasklist_lock that is touched in allover places.

As a temporary workaround, this patch provides the way to defer the
async signal notification in a work.  The new helper functions,
snd_fasync_helper() and snd_kill_faync() are replacements for
fasync_helper() and kill_fasync(), respectively.  In addition,
snd_fasync_free() needs to be called at the destructor of the relevant
file object.

Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema.  This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.

Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.

While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

VA Macro fsgen clock is supplied to other LPASS Macros using proper
clock apis, however the internal user uses the registers directly without
clk apis. This approch has race condition where in external users of
the clock might cut the clock while VA macro is actively using this.

Moving the internal usage to clk apis would provide a proper refcounting
and avoid such race conditions.
