vc/google: Decouple DSM_CALIB from CHROMEOS
DSM (Dynamic Speaker Management) uses calibration parameters stored in a VPD (Vital Product Data) FMAP region to configure the audio output via an ACPI _DSD table. This has no dependency on a ChromeOS, and can be used by Linux/Windows drivers if appropriately configured. Remove the dependency of DSM_CALIB (and the calibration file) on CHROMEOS and replace it with VPD, so that non-CHROMEOS builds can utilize this feature as well. Move files from underneath vc/google/chromeos to underscore the point. TEST=build/boot google/nightfury, dump ACPI, verify DSM calibraton parameters present in _DSD table.
