Now sof kernel driver supports two dmic dai links: DMIC01 PIN,
which supports rate of 48k, and DMIC16k Pin, which supports rate
of 16k. And if four channels dmic is used, we only support one dmic
dai link. CHANNELS would check in intel-generic-dmic to generate
the correct topology file.

This patch alters the volume IPC and ramp to use sQ8.16 gain
values instead of previous Q2.16 kind of unsigned gain value.
The driver has never set the min/max volume values in volume
new() IPC so the macro values VOL_MAX (+42 dB) and VOL_MIN (mute)
are used instead as limits.
The overflow in generic C code with s16 format is fixed. The
comments about volume Q format are updated.
The optimimized xt-xcc version of volume is changed to use 64
bits for multiply result to avoid loss of LSB bits in left shift
after multiply. With 64 bit result there is no need to scale the
volume multiplier as it was done with use of 32 bit multiply
result.
The cmocka volume type is changed to signed integer to match
component type used in this patch. The xtensa AE integer types
are signed so better to avoid unsigned gain values. The volume
scale in reference volume does a small error and cannot handle
above 0 dB max so it is changed as well. The test levels are
changed to exercise gains above and below 0 dB.

The macro in tlv.m4 defines a volume scale from -64 dB with 2 dB
steps for playback pipelines. Hence the name m90s3 is incorrect.
The new name m64s2 is a correct description of the defined volume
scale. It's useful since there's another volume scale defined for
capture pipelines.

This patch replaces the -64 to 0 dB volume scale for capture with
more practical -50 to +30 dB gain. The step is 1 dB. It allows to
compensate for different microphone model sensitivities when constant
acoustical decibels to digital decibels level is needed in a
microphone capture application.

Changes implementation of dw_dma_stop function for
baytrail and cherrytrail platforms. On this platforms
we cannot simply disable channel during transfer,
because it will hang DMA. Previously we were waiting
for transfer finish, which could take up to one period
size (1 ms in most cases). This patch uses suspend and
drain FIFO mechanism, which lowers time needed to stop
DMA channel to steady ~0.34 ms.
