In current implementation, there is a overhead of maintaining caldata
in the filesystem manually. To eliminate this overhead, for pci based
chipsets, if calibration data is present in EEPROM, indicate firmware
to download and read caldata from EEPROM. If the caldata is present in
EEPROM, host is notified in the target capability.
Upon this, the download request for the type ATH12K_QMI_FILE_TYPE_EEPROM
is sent to firmware.
