This patch creates sof_apl_hdmi.m4 to define topology for 3 playback
pipelines, FE and BE links for HDMI/DisplayPort(DP) audio. This can be
a reference to verify audio over HDMI/DP on APL platforms.
The HDMI/DP frontends are named as HDMIx, to reuse the generic HDA DSP
machine driver which checks the link names and will do extra
initialization on HDMI/DP frontends if "HDMI" is found in the link name.
This m4 does't include topology for using external HD-A analog codecs. We
will create another m4 file to include both HDA display and analog audio.

This SPDIF transmitter/receiver is used by the HifiBerry DIGI+ and
DIGI IO. The wm8804 operates as bit clock and frame master.
TODO in future update: add support for capture on the DIGI+ IO (this
may be done with a different topology file to avoid confusing users
with a non-working PCM capture patch)

The APL and GLK topologies are identical except for a swap of SSPs and MCLKs.
Tested on Reef and GLK
TODO:
1. there is currently a kernel bug where only duplex pipelines can be
assigned to the same PCM number. For now mark DMIC as device 99 to
track this is a work-around to be modified in the near future
2. Edit the Virtual routes/widgets to remove kernel warnings (no
functional impact)

Add a multi-stream topology for GLK with speaker on SSP1, headset on
SSP2 and DMIC. Only playback pipelines on SSP1/2 for now. Capture
pipelines to be added later.

Here add topology file for apollolake GP-MRB platform,
it is initial version, we only support one playback
and one capture PCM pipeline at the moment,
with SSP/DAI set to tdm8-32le-48kHz
(active on first 4 slots for both transmit and receive).

Add support in topology to define different memory capabilities that can
be included by standard pipeline definitions to set platform specific
capabilities for buffers.
This patch allows memory capabilities to be defined for each platform and
included by all pipeline definitions.

Move testing pipelines into a test directory and reuse test scaffolding
so that they can be used to test multiple components on multiple target
with multiples configs.
Test topology scafolding are now pre-processed using a script to generate
the ALSA conf format with the various changes for each test case.

At some point we should have a better way of relying on common parts but
for now add a passthrough shortcut directly usable with machine drivers

Add support to build topology text files into binary files understood
by the drivers. This is a two stage build, the first stage is to
pre-process the files with M4 into regular alsa-conf format and the second
stage is to compile with the alsa topology compiler.
