ASoc: tas2783A: fw name based on system details

Browse Source 
The firmware file for tas2783A contains the device
and algorithm settings. So the firmware files are unique
for a system and driver should have the ability to
distinctly identify and pick the right firmware.

This commit adds the method to uniquely identify the
firmware for a system based on the below format.
 <Subsystem>-<Link>-<Unique>.bin

* Subsystem is the PCI device subsystem-id
* Link is the SoundWire link id on which the device recides.
* Unique is the SoundWire slave unique id in the system.
