ALSA: hda/realtek: Support ACPI Notification framework via component binding

Browse source

For systems which have support for ACPI notifications, add a mechanism to
register a handler for ACPI notifications and then call the acpi_notify
api on the bound components.

Registering a handler in the Realtek HDA driver, allows a single handler to
be registered, which then calls into all the components, rather than
attempting to register the same handler multiple times, once for each
component.
