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.
