FW advertizes calibration data support from EEPROM through 
'eeprom_read_timeout' in
QMI FW Capability message. Ath11k sends BDF download request with file 
type
'ATH11K_QMI_FILE_TYPE_EEPROM'. FW has logic to read calibration data 
from EEPROM and
process the calibration data. FW takes more time to process the 
calibration data from
EEPROM so increase QMI timeout to 10msec.
