ASoC: q6afe-clocks: add q6afe clock controller
q6afe already exposes lpass clocks, however this was not presented
as proper clock controller driver. This patch basically adds clock
controller support for q6afe clocks.

This is useful for other drivers like lpass digital codec or lpass
lowpower island drivers to request or vote for these clocks.

ASoC: q6asm: make commands specific to streams
Each ASM session can have multiple streams attached to it,
current design was to allow only one static stream id 1 per each session.
However for use-case like gapless, we would need 2 streams to open per session.

This patch converts all the q6asm apis to take stream id as argument
to allow multiple streams to open on a single session, This is useful
for gapless playback cases.

Now the dai driver can specify which stream id for each command.

ASoC: q6routing: add dummy register read/write function
Most of the DAPM widgets for DSP ASoC components reuse reg field
of the widgets for its internal calculations, however these are not
real registers. So read/writes to these numbers are not really
valid. However ASoC core will read these registers to get default
state during startup.

With recent changes to ASoC core, every register read/write
failures are reported very verbosely. Prior to this fails to reads
are totally ignored, so we never saw any error messages.

To fix this add dummy read/write function to return default value.

ASoC: dt-bindings: q6asm: Add Q6ASM_DAI_{TX_RX, TX, RX} defines
Right now the direction of a DAI has to be specified as a literal
number in the device tree, e.g.:

	dai@0 {
		reg = <0>;
		direction = <2>;
	};

but this does not make it immediately clear that this is a
playback/RX-only DAI.

Actually, q6asm-dai.c has useful defines for this. Move them to the
dt-bindings header to allow using them in the dts(i) files.
The example above then becomes:

	dai@0 {
		reg = <0>;
		direction = <Q6ASM_DAI_RX>;
	};

which is immediately recognizable as playback/RX-only DAI.

ASoC: q6asm: handle EOS correctly
Successful send of EOS command does not indicate that EOS is actually
finished, correct event to wait EOS is finished is EOS_RENDERED event.
EOS_RENDERED means that the DSP has finished processing all the buffers
for that particular session and stream.

This patch fixes EOS handling!

ASoC: q6dsp6: q6afe-dai: add missing channels to MI2S DAIs
For some reason, the MI2S DAIs do not have channels_min/max defined.
This means that snd_soc_dai_stream_valid() returns false,
i.e. the DAIs have neither valid playback nor capture stream.

It's quite surprising that this ever worked correctly,
but in 5.7-rc1 this is now failing badly: :)

Commit 0e9cf4c452ad ("ASoC: pcm: check if cpu-dai supports a given stream")
introduced a check for snd_soc_dai_stream_valid() before calling
hw_params(), which means that the q6i2s_hw_params() function
was never called, eventually resulting in:

    qcom-q6afe aprsvc:q6afe:4:4: no line is assigned

... even though "qcom,sd-lines" is set in the device tree.

Commit 9b5db059366a ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported")
now even avoids creating PCM devices if the stream is not supported,
which means that it is failing even earlier with e.g.:

    Primary MI2S: ASoC: no backend playback stream

Avoid all that trouble by adding channels_min/max for the MI2S DAIs.

ASoC: qcom: q6asm-dai: Add SNDRV_PCM_INFO_BATCH flag
At the moment, playing audio with PulseAudio with the qdsp6 driver
results in distorted sound. It seems like its timer-based scheduling
does not work properly with qdsp6 since setting tsched=0 in
the PulseAudio configuration avoids the issue.

Apparently this happens when the pointer() callback is not accurate
enough. There is a SNDRV_PCM_INFO_BATCH flag that can be used to stop
PulseAudio from using timer-based scheduling by default.

According to https://www.alsa-project.org/pipermail/alsa-devel/2014-March/073816.html:

    The flag is being used in the sense explained in the previous audio
    meeting -- the data transfer granularity isn't fine enough but aligned
    to the period size (or less).

q6asm-dai reports the position as multiple of

    prtd->pcm_count = snd_pcm_lib_period_bytes(substream)

so it indeed just a multiple of the period size.

Therefore adding the flag here seems appropriate and makes audio
work out of the box.
