ASoC: Intel: avs: Abstract IPC handling

Servicing IPCs on CNL platforms and onward differs from the existing
one. To make room for these, enrich platform descriptor with fields
representing crucial IPC registers and utilize them throughout the code.

While cleaning up device descriptors, reduce the number of code lines by
assigning 'min_fw_version' within a single line.

ASoC: Intel: avs: Disable DSP before loading basefw

When audio controller is passed-through to the guest machine in
virtualized environment, the basefw load will fail the next time guest
OS reboots. Disable the DSP main core before loading the base firmware
to sanitize the environment.

ASoC: Intel: avs: Enact power gating policy

Update all firmware loading functions to also account for the power
gating policy. As module loading routine is missing the chicken bits
manipulation entirely, add the entire set there.

ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer

The SPIB and DRMS capabilities are orthogonal to the DSP enablement
and can be used whether the stream is coupled or not.

The existing code partitioning makes limited sense, the capabilities
are parsed at the sound/hda level but helpers are located in
sound/hda/ext.

This patch moves all the SPIB/DRMS functionality to the sound/hda
layer. This reduces the complexity of the sound/hda/ext layer which is
now limited to handling the multi-link extensions and stream
coupling/decoupling helpers.

Note that this is an iso-functionality code move and rename, the
HDaudio legacy driver would need additional changes to make use of
these capabilities.

ASoC: Intel: avs: APL-based platforms support

Define handlers specific to cAVS 1.5+ platforms, that is, APL and
similar platforms. These differ from SKL-alike ones in terms of AudioDSP
firmware generation and thus the '+' suffix. Introduciton of IMR,
removal of CLDMA, D0IX support and monolithic-ation of library/module
code are most impactful but are not the only changes brought with this
newer generation. Some generic and 1.5 operations are being re-used to
reduce code size.

ASoC: Intel: avs: Account for libraries when booting basefw

Not all modules are part of base firmware. Some are part of loadable
libraries. These need to be loaded after base firmware reports ready
status through FW_READY notification.

Their loading process is similar to the base firmware's one. Request the
binary file, verify and strip the manifest and load the actual code into
DSP memory with help of CLDMA or HD-Audio render stream, depending on
audio device generation.

List of libraries needed for loading is obtained through the topology -
vendor sections specifying the name of firmware files to request.

ASoC: Intel: avs: Code loading over HDA

Compared to SKL and KBL, more recent cAVS platforms are meant to re-use
one of HDAudio streams during boot procedure causing CLDMA to become
obsolete. Once transferred, given stream is returned to pool available
for audio streaming.

Module loading handler is stub as library and module code became
inseparable in later firmware generations.
