[0/5] ALSA: hda: New NHLT functions and cleanup

Message

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

Few cleanups accompany the above:
First, drop device pointer usage in NHLT interface as those function
don't really make use of it. Work is done to align NHLT-struct naming
with other, commonly used ACPI-structs. While cleaning up, don't forget
about "is DMIC in NHLT?" check. No need to check for channel count or
anything DMIC-configuration related, just straight up verify link_type
presence.

  ALSA: hda: Follow ACPI convention in NHLT struct naming
  ALSA: hda: Fill gaps in NHLT endpoint-interface
