For distributions, we need one place where we can decide which driver will be activated for the auto-configation of the Intel's HDA hardware with DSP. Actually, we cover three drivers:
- Legacy HDA
- Intel SST
- Intel Sound Open Firmware (SOF)
All those drivers registers similar PCI IDs, so the first driver probed from the PCI stack can win. But... it is not guaranteed that the correct driver wins.
This commit changes Intel's NHLT ACPI module to a common DSP probe module for the Intel's hardware. All above sound drivers calls this code. The user can force another behaviour using the module parameter 'dsp_driver' located in the 'snd-intel-dspcfg' module.
This change allows to add specific dmi checks for the specific systems. The examples are taken from the pull request:

Tested on Lenovo Carbon X1 7th gen.
