Some ARM versions of Chromebook need to download a new calibration data from host driver to firmware. They do have EEPROM but still need a piece of new calibration data in test mode. The cal-data is platform dependent. It's simpler and more feasible to use device tree based cal-data instead of configuration file based cal-data. This patch remove configuration file based cal-data downloading and replace it using cal-data from device tree. When CONFIG_OF is not selected, or the specific property is not present in the device tree, the calibration downloading will not happen.
