The host period bytes value needs to be passed to firmware.
However current implementation uses this field for different
purpose - to indicate whether FW should send stream position
to the host. Therefore this patch introduces another field
"no_stream_position", a boolean value aimed to store information
about position tracking. This way host_period_bytes preserves its
original value.

In a number of debug cases, the DMA-based trace can add problems
(e.g. with HDaudio channel allocation). It also generates additional
traffic on the bus and if the DMA handling is unreliable will prevent
audio use-cases from working normally. Using the trace also requires
tools to be installed on the target.

The trace can be instead handled as dynamic debug. We can use a
Kconfig to force the trace to be enabled in all cases, or use a module
parameter to enable it on a need-basis, e.g. by setting "options
snd_sof sof_debug=0x1" in a /etc/modprobe.d file.

On stream stop currently we stop the DMA first followed by the CPU DAI.
This can cause underflow (playback) or overflow (capture) on the DAI side
as the DMA is no longer feeding data while the DAI is still active.
It can be observed easily if the DAI side does not have FIFO (or it is
disabled) to survive the time while the DMA is stopped, but still can
happen on relatively slow CPUs when relatively high sampling rate is used:
the FIFO is drained between the time the DMA is stopped and the DAI is
stopped.

It can only fixed by using different sequence within trigger for 'stop' and
'start':
case SNDRV_PCM_TRIGGER_START:
case SNDRV_PCM_TRIGGER_RESUME:
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
	Trigger order: dai_link, DMA, CPU DAI then the codec

case SNDRV_PCM_TRIGGER_STOP:
case SNDRV_PCM_TRIGGER_SUSPEND:
case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
	Trigger order: codec, CPU DAI, DMA then dai_link

"rtd"      is handled by soc_xxx_pcm_runtime(), and
"rtd->dev" is handled by soc_rtd_xxx().

There is no reason to separate these, and it makes code complex.

Here soc_rtd_free() (A) which frees rtd->dev is called from

Then, it is using dev_registered flags to avoid multi kfree() (2).
This is no longer needed if we can merge these functions.

LSB-valid 16bit, MSB shift-out first, frame sync asserting with
the first bit of the frame, data shifted with the posedge of
bit clock, 44.1 kHz or 48 kHz signals from SAI1 in left justified
format; and it provides the SNR target as no more than 20dB for
the signals below 10 kHz. The signals above 10 kHz will have
worse THD+N values.

MQS provides only simple audio reproduction. No internal pop,
click or distortion artifact reduction methods are provided.
