Clean up the driver with the new managed buffer allocation API.
The normal playback streams need a workaround for the aligned buffer,
and cannot apply the straight snd_pcm_lib_malloc() stuff, so they
remain untouched, while other streams are converted to the new managed
mode.
Most of hw_params and hw_free callbacks became superfluous and got
dropped.

The HD-audio CORB/RIRB communication was programmed in a way that was
documented in the reference in decades ago, which is essentially a
polling in the waiter side. It's working fine but costs CPU cycles on
some platforms that support only slow communications. Also, for some
platforms that had unreliable communications, we put longer wait time
(2 ms), which accumulate quite long time if you execute many verbs in
a shot (e.g. at the initialization or resume phase).
This patch attempts to improve the situation by introducing the
standard waitqueue in the RIRB waiter side instead of polling. The
test results on my machine show significant improvements. The time
spent for "cat /proc/asound/card*/codec#*" were changed like:
* Intel SKL + Realtek codec
before the patch:
0.00user 0.04system 0:00.10elapsed 40.0%CPU
after the patch:
0.00user 0.01system 0:00.10elapsed 10.0%CPU
* Nvidia GP107GL + Nvidia HDMI codec
before the patch:
0.00user 0.00system 0:02.76elapsed 0.0%CPU
after the patch:
0.00user 0.00system 0:00.01elapsed 17.0%CPU
So, for Intel chips, the total time is same, while the total time is
greatly reduced (from 2.76 to 0.01s) for Nvidia chips.
The only negative data here is the increase of CPU time for Nvidia,
but this is the unavoidable cost for faster wakeups, supposedly.

Nicholas Johnson reports a null pointer deref as well as a refcount
underflow upon hot-removal of a Thunderbolt-attached AMD eGPU.
He's bisected the issue down to commit 586bc4aab8 ("ALSA: hda/hdmi -
fix vgaswitcheroo detection for AMD").
The commit iterates over PCI devices using pci_get_class() and
unreferences each device found, even though pci_get_class()
subsequently unreferences the device as well. Fix it.

The loop optimizer seems to go astray here, and produces some warnings
that don't seem valid.
Still, the code can be simplified -- just clear the whole array at the
