ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection
For HDaudio and Skylake drivers, add module parameter "pci_binding" When pci_binding == 0 (AUTO), the PCI class/subclass info is used to select drivers based on the presence of the DSP. pci_binding == 1 (LEGACY) forces the use of the HDAudio legacy driver, even if the DSP is present. pci_binding == 2 (ASOC) forces the use of the ASOC driver. The information on the DSP presence is bypassed. The value for the module parameter needs to be identical for both drivers. This parameter is intended as a back-up solution if the automatic detection fails or when the DSP usage fails. Such cases should be reported on the alsa-devel mailing list for analysis.
