dm: acpi: Add support for the NHLT table

The Intel Non-High-Definition-Audio Link Table (NHLT) table describes the
audio codecs and connections in a system. Various devices can contribute
information to produce the table.

Add core support for this, based on a structure which is built up through
calls to the driver.
