ath10k: add BMI parameters to fix calibration from DT/pre-cal
QCA99X0, QCA9888, QCA9984 supports calibration data in either OTP or DT/pre-cal file. Current ath10k supports Calibration data from OTP only. If caldata is loaded from DT/pre-cal file, fetching board id and applying calibration parameters like tx power gets failed. error log: [ 15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2 [ 15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2) This patch adds calibration data support from DT/pre-cal file. Below parameters are used to get board id and applying calibration parameters from cal data. EEPROM[OTP] FLASH[DT/pre-cal file] Cal param 0x700 0x10000 Board id 0x10 0x8000 Tested on QCA9888 with pre-cal file.
