The bus + qmi-chip-id + qmi-board-id is not enough to identify the correct board data file on IPQ6018 based devices. Multiple different boards share the same values. Only the original reference designs can currently be identified and loaded from the board-2.bin. But these will not result in the correct calibration data when combined with the pre-calibration data from the device. An additional "variant" information has to be provided to select the correct board data for a design which was modified by an ODM. This follows the same approach as ath10k.
