Matti Laakso 2ea98fc39b ar71xx: fix 5 GHz Wi-Fi on NBG6716
Some NBG6716 do not have ath10k calibration data in flash, only in chip
OTP. To determine if flash has a valid calibration data, the first two
bytes telling the length of the calibration data are checked against the
requested length. If the lengths match, calibration data is valid and
read from flash.
