When a single clock source is shared among several endpoints, we have
to keep the same rate on all active endpoints as long as the clock is
being used. For dealing with such a case, this patch adds one more
check in the hw params constraint for the rate to take the shared
clocks into account. The current rate is evaluated from the endpoint
list that applies the same clock source.

The commit f87e7f2589 ("ALSA: hda - Improved position reporting on
SKL+") changed the PCM position report for SKL+ chips to use DPIB, but
according to Pierre, DPIB is no best choice for the accurate position
reports and it often reports too early. The recommended method is
rather the classical position buffer.
This patch makes the PCM position reporting on SKL+ back to the
position buffer again.

The position reporting on Intel Skylake and later chips via
azx_get_pos_skl() contains a udelay(20) call for the capture streams.
A call for this alone doesn't sound too harmful. However, as the
pointer PCM ops is one of the hottest path in the PCM operations --
especially for the timer-scheduled operations like PulseAudio -- such
a delay hogs CPU usage significantly in the total performance.
The code there was taken from the original code in ASoC SST Skylake
driver blindly. The udelay() is a workaround for the case where the
reported position is behind the period boundary at the timing
triggered from interrupts; applications often expect that the full
data is available for the whole period when returned (and also that's
the definition of the ALSA PCM period).
OTOH, HD-audio (legacy) driver has already some workarounds for the
delayed position reporting due to its relatively large FIFO, such as
the BDL position adjustment and the delayed period-elapsed call in the
work. That said, the udelay() is almost superfluous for HD-audio
driver unlike SST, and we can drop the udelay().
Though, the current code doesn't guarantee the full period readiness
as mentioned in the above, but rather it checks the wallclock and
detects the unexpected jump. That's one missing piece, and the drop
of udelay() needs a bit more sanity checks for the delayed handling.
This patch implements those: the drop of udelay() call in
azx_get_pos_skl() and the more proper check of hwptr in
azx_position_ok(). The latter change is applied only for the case
where the stream is running in the normal mode without
no_period_wakeup flag. When no_period_wakeup is set, it essentially
ignores the period handling and rather concentrates only on the
current position; which implies that we don't need to care about the
period boundary at all.

The code for hdac_ext_stream seems inherited from hdac_stream, and
similar locking issues are present: the use of the bus->reg_lock
spinlock is inconsistent, with only writes to specific fields being
protected.
Apply similar fix as in hdac_stream by protecting all accesses to
'link_locked' and 'decoupled' fields, with a new helper
snd_hdac_ext_stream_decouple_locked() added to simplify code
changes.

snd_usb_find_clock_source and snd_usb_find_clock_selector are helper
macros that look at an entity id and validate that this entity id is
in fact a clock source or a clock selector. The present comments
inside __uac_clock_find_source give the reader the impression we're
looking for an entity id.
We're looking for an entity id indeed, the clock source, but since
__uac_clock_find_source is recursive, we're also looking *at* the
entity ids, in the search for the one clock source.
Fix the comment so we don't give readers a wrong idea.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
In this case this is not actually dynamic size: all the operands
involved in the calculation are constant values. However it is better to
refactor this anyway, just to keep the open-coded math idiom out of
code.
So, use the struct_size() helper to do the arithmetic instead of the
argument "size + size * count" in the kzalloc() function.
Also, take the opportunity to refactor the declaration variables to make
it more easy to read.

USB-audio driver assumes that the normal resume would preserve the
device configuration while reset_resume wouldn't, and tries to restore
the mixer elements only at reset_resume callback. However, this seems
too naive, and some devices do behave differently, resetting the
volume at the normal resume; this resulted in the inconsistent volume
that surprised users.
This patch changes the mixer resume code to handle both the normal and
reset resume in the same way, always restoring the original mixer
element values. This allows us to unify the both callbacks as well as
dropping the no longer used reset_resume field, which ends up with a
good code reduction.
A slight behavior change by this patch is that now we assign
restore_mixer_value() as the default resume callback, and the function
is no longer called at reset-resume when the resume callback is
overridden by the quirk function. That is, if needed, the quirk
resume function would have to handle similarly as
restore_mixer_value() by itself.
