google/chromeos: Add a library to get DSM calibration data
On ChromeOS, there will be VPD values for DSM (dynamic speaker management) calibration data. They are resistor calibration values and temperature during calibration.
These VPD fields use "dsm_calib," prefix.
Known keys are
"dsm_calib_r0_0" "dsm_calib_r0_1" "dsm_calib_r0_2" "dsm_calib_r0_3" "dsm_calib_temp_0"
The values are unsigned decimal numbers. This library will be used for RT1011 device driver in the patch series.
BUG=b:140397934 BRANCH=none TEST=On Helios, with patch series, check realtek,r0_calib and realtek,temperature_calib are available to rt1011 codec driver.
