ALSA: virtio: handling control and I/O messages for the PCM device
The driver implements a message-based transport for I/O substream
operations. Before the start of the substream, the hardware buffer is
sliced into I/O messages, the number of which is equal to the current
number of periods. The size of each message is equal to the current
size of one period.
I/O messages are organized in an ordered queue. The completion of the
I/O message indicates an elapsed period (the only exception is the end
of the stream for the capture substream). Upon completion, the message
is automatically re-added to the end of the queue.

ALSA: virtio: build PCM devices and substream hardware descriptors
Like the HDA specification, the virtio sound device specification links
PCM substreams, jacks and PCM channel maps into functional groups. For
each discovered group, a PCM device is created, the number of which
coincides with the group number.
Introduce the module parameters for setting the hardware buffer
parameters:
pcm_buffer_ms [=160]
pcm_periods_min [=2]
pcm_periods_max [=16]
pcm_period_ms_min [=10]
pcm_period_ms_max [=80]
