dt: bindings: add new dt entry for pre calibration in qcom, ath10k.txt
There two things done in this patch, 1) Existing device tree entry 'qcom,ath10k-calibration-data' carries not only calibration data, it carries board specific data too. So, make appropriate update in doc. 2) ipq4019 wifi needs new devie tree entry to carry calibration data alone (called pre cal data, it doesn't include any other info). Using 'qcom,ath10k-calibration-data' for ipq4019 would alter the purpose of it. Hence, add new device tree entry called 'qcom,ath10k-pre-calibration-data' to carry only pre calibration data.
