	Mirror capabilities provided for PCI devices, so that distributions can select which ACPI driver is loaded at run-time with kernel parameters and DMI tables instead of forcing a build-time selection. The "legacy" option supported for HDaudio has no meaning here and will be ignored. The 'SST' driver based on closed-source firmware has the priority to avoid any impact on users, and the choice to use SOF is strictly opt-in. This may change at some point when the 'SST' driver is deprecated on Baytrail/Cherrytrail.
