ASoC: Intel: avs: Machine board registration
AVS driver operates with granular audio card division in mind.
Super-card approach (e.g.: I2S, DMIC and HDA DAIs combined) is
deprecated in favour of individual cards - one per each device. This
provides necessary dynamism, especially for configurations with number
of codecs present and makes it easier to survive auxiliary devices
failures - one card failing to probe does not prevent others from
succeeding.
All boards spawned by AVS are unregistered on ->remove(). This includes
dummy codecs such as DMIC.
As all machine boards found in sound/soc/intel/boards are irreversibly
tied to 'super-card' approach, new boards are going to be introduced.
This temporarily increases number of boards available under /intel
directory until skylake-driver becomes deprecated and removed.
