This patch impacts topologies sof-apl-nocodec, sof-apl-da7219, and
sof-glk-da7219 those use the pipe-passthrough-capture macro for DMIC.
The PCM saple rate is limited to 48 kHz (was 8 - 192 kHz). The capture
channels count can be only PIPELINE_CHANNELS (was 1 - PIPELINE_CHANNELS).
This prevents corrupted audio capture that happens when DMIC topology
parameters and capture parameters differ. It happens because DMIC FIFOs
drop samples or add unwanted samples when the configuration does not match.
In sof-apl-nocodec topology the PIPELINE_CHANNELS is set to 2 that
matches the configuration.

This patch addresses the following:
1. Move PCM_PLAYBACK_ADD to pcm.m4
The macro was in the wrong m4 file (buffer.m4)
2. Remove pipeline_id argument and "index" from SectionPCM
"index" is not a member of struct snd_soc_tplg_pcm. So this
information is not used in the kernel at all.
Secondly, the PCM ID could be associated with more than
one pipeline especially in the case of DUPLEX PCM's. So better
to remove it to avoid ambiguities.
3. Remove dai_id
This dai_id is the ID given to the CPU DAI when the FE DAI link
is created. In the case of SOF, we should use an linearly increasing
unique ID for CPU DAI ID's. If this argument is omitted, the kernel
automatially assignes an ID based on the component->num_dai
which is linearly incremented every time a new DAI link is added.
4. Finally update users to align with the new definitions.

Add DMIC capture pipeline for DMIC01 to the apl nocodec topology.
DMIC16k to be added later.

For some reason parts of the topology were commented out. Make sure
all 6 SSPs are enabled.
Tested on Up2 with a LogicPro-based check on SSP5 (only interface
accessive on the HAT connector)

Rename SAMPLE_BITS macro to a more generic CONFIG_DATA macro for SSP
to also include the mclk id.
Also modify users of the macro with the new name.

This patch makes changes to DAI config in topology to separate out
SSP specific params from common params in preparation for other
DAI types coming soon.

ALSA-lib introduced new definitions to work around an logical
inversion for master/slave definitions. see e.g. commit 3778a30bb00
('ASoC: topology: Fix bclk and fsync inversion in
set_link_hw_format()')
Make sure clarifications are reflected in the topology files
bclk/fsync slave -> codec_slave
mclk slave -> codec_mclk_in
This patch requires the use of the latest alsa-lib git master (v1.1.6
does not contain the relevant patches).
This patch also requires an updated kernel.
