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

Browse Source 
The existing 'tplg_path' module parameter can be used to load
alternate firmware files, be it for development or to handle
OEM-specific or board-specific releases. However the topology filename
is either hard-coded in machine descriptors or modified by specific
DMI-quirks.

For additional flexibility, this patch adds the 'tplg_filename' module
parameter to override topology names.

To avoid any confusion between DMI- and parameter-override, a variable
rename is added.
