Set of patches to enable DMIC capture on different hardware
configurations.
Information about supported DMIC configuration is read from NHLT and
correct pipeline configuration is selected automatically.
Also, adding additional option for topology binary name which is
based on used machine driver.

Changes in v2:
- removed patch 1/4 swapping machine device and platform device
  registration order
- alt_tplg_name creation now uses different field to read machine driver
  name
- including of <sound/soc-acpi.h> moved to different patch

Changes in v3:
- cosmetic changes in skl-topology.c file

Changes in v4:
- refactored patch 2/3 to use one common helper function to deal with both
  set and get pipe configuration operations, as suggested by Pierre
- adjusted patch 3/3 to also use this helper function for DMIC pipes
- added comment in patch 3/3 explaining the change of access rights for
  DMIC enums

Changes in v5:
- fixed alignment issue in patch 2/3
- addressed "checkpatch.pl --strict" warnings in patches
