ASoC: SOF: core: Add fw, tplg and ipc type override parameters

The different bus type helpers define their own override parameters for
firmware name/path, topology name/path. sof-pci-dev covers all while others
just a subset.
There is no technical reason to do that since these are generic platform
independent parameters.

Add the override module options to core (snd-sof module) and update the
description for the device helper modules as deprecated.
