[PATCH v4 0/3] ALSA: hda: New NHLT functions and cleanup

Changes add two crucial functions: endpoint presence-check and
retrieval of endpoint's BLOB (hardware configuration) to NHLT API.

Outside of that, "is DMIC in NHLT?" check is being re-visited. No need
to check for channel count or anything DMIC-configuration related, just
straight up verify link_type presence.

Changes in v4:
- patch renaming nhlt_acpi_table struct to acpi_nhlt_table has been
  dropped due to naming conflicts with other parts of the kernel
- revoked previously appended tags from Mark and Pierre as every patch
  required an update due to above

Changes in v3:
- no code changes
- appended Mark's Acked-by tag for patch 4/4
- appended Pierre's Reviewed-by tag for all patches

Changes in v2:
- patch "ALSA hda: Drop device-argument in NHLT functions" has been
  dropped
- updated newly added declarations in intel-nhlt.h so warning:
  "no-previous-prototype-for-function" and error:
  "use-of-undeclared-identifier" are no longer observed when
  CONFIG_SND_INTEL_NHLT is not enabled
- added Mark's tag to the last patch of the series
