Make use of UAC3 Power Domains associated to an Audio Streaming

associated to that substream to state D1. When audio is being transferred
(from hw_params onwards), the Power Domain will be set to D0 state.
This is the way the host lets the device know which Terminal

manage its own internal resources on that UAC3 Power Domain.

The virmidi sequencer stuff tries to translate the rawmidi bytes to

this was the cause of a CPU soft lockup that had been reported and
fixed recently.
Although we've fixed the soft lockup by putting the temporary unlock
and cond_resched(), it's rather a quick band aid. In this patch,
meanwhile, the event parsing and delivery process is offloaded to a
dedicated work, and the trigger callback just kicks it off. It has
three merits, at least:
- The processing is always done in a sleepable context, which can
assure the event delivery with non-atomic flag without hackish
is_atomic() usage.

ALSA: hda/realtek - Yet another Clevo P950 quirk entry
The PCI SSID 1558:95e1 needs the same quirk for other Clevo P950
models, too. Otherwise no sound comes out of speakers.

ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc()
snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with
somewhat special for vmalloc handling, but in the end, this turned to
just the default handler, i.e. NULL. As the situation has never
changed over decades, let's rip it off.

ALSA: rawmidi: Use kvmalloc() for buffers
The size of in-kernel rawmidi buffers may be big up to 1MB, and it can
be specified freely by user-space; which implies that user-space may
trigger kmalloc() errors frequently.
This patch replaces the buffer allocation via kvmalloc() for dealing
with bigger buffers gracefully.

ALSA: rawmidi: Minor code refactoring
Unify a few open codes with helper functions to improve the
readability. Minor behavior changes (rather fixes) are:
- runtime->drain clearance is done within lock
- active_sensing is updated before resizing buffer in
SNDRV_RAWMIDI_IOCTL_PARAMS ioctl.
Other than that, simply code cleanups.

ALSA: rawmidi: Simplify error paths
Apply the standard idiom: rewrite the multiple unlocks in error paths
in the goto-error-and-single-unlock way.
Just a code refactoring, and no functional changes.

ALSA: rawmidi: Tidy up coding styles
Just minor coding style fixes like removal of superfluous white space,
adding missing blank lines, etc. No actual code changes at all.
