dt: bindings: add new dt entry for ath10k calibration variant
The bus + bmi-chip-id + bmi-board-id is not enough to identify the correct board data file on QCA4019 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 (via SMBIOS or DT) to select the correct board data for a design which was modified by an ODM.
