lib: NHLT ACPI table support
Intel's SST (Smart Sound Technology) employs audio support
which may not consist of HDA. In order to define the topology
of the audio devices (mics, amps, codecs) connected to the
platform a NHLT specification was created to pass this
information from the firmware to the OS/userland.
BUG=chrome-os-partner:44481
BRANCH=None
TEST=Tested on glados. Audio does get emitted and some mic recording
works.
