Add debug parameter for snd-sof-acpi.
One of the usages for this debug parameter to disable pm_runtime,
which can be useful for platform bringup, or keep the parent device
active while enabling pm_runtime for child devices (e.g. with
SoundWire or MFD). This can also be useful to measure suspend-resume
latencies or child devices.

We have duplicated code in multiple locations (atom, machine drivers,
SOF) to detect Baytrail, Cherrytrail and other SOCs. This is not very
elegant, and introduces dependencies on CONFIG_X86 that prevent
COMPILE_TEST from working.
Add common helpers to provide same functionality in a cleaner
way. This will also help support the DMI-based quirks being introduced
to handle SOF/SST autodetection.
