ALSA: hda: cs35l41: Add notification support into component binding

Some systems support a notification from ACPI, which can be used
for different things.

Only one handler can be registered for the acpi notification, but all
amps need to receive that notification, we can register a single handler
inside the component master, so that it can then notify through the
component framework.

This is required to support mute notifications from ACPI.
