ASoC: SOF: sof-pci-dev: add parameter to override firmware filename

Browse Source 
The existing 'fw_path' module parameter can be used to load alternate
firmware files, be it for development or to handle OEM-specific or
board-specific releases. The firmware name is however non-modifiable
and defined by platform-specific descriptors.

For additional flexibility during development or enable quirks, this
patch adds the 'fw_filename' module parameter to override default
firmware names.
