ASoC: Intel: avs: Switch to acpi-nhlt

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The change is based on rafael/acpi-nhlt [1] immutable branch which
Rafael kindly prepared for me. Without the topmost changes to ACPI/NHLT,
the patches present will fail to compile.

Recent changes for the ACPI tree [2] refactored interfaces of the NHLT
table. Currently we have two implementations - one found in acpi
subsystem (unused) and one in sound/hda/. As NHLT is part of ACPI, idea
is to make the former useful and then switch all users of existing
sound/hda/intel-nhlt.c to this new interface over time and remove the
duplicate afterward.
