ath10k and ath11k support reading calibration variants from the device tree to locate the correct Board Description File (BDF). The ath12k-wsi binding already describes using qcom,calibration-variant but it is not implemented in the driver. Many ath12k designs expose all the radios under a single phy, each of which typically require a separate BDF. Without this, the radios may not come up or will not be calibrated correctly. Fix this by parsing the device tree for the generation-agnostic qcom,calibration-variant. This allows the driver to properly select, read and apply the correct BDF. Additionally, the ath12k-wsi binding documentation describes using the generation-specific qcom,ath12k-calibration-variant binding as well as the generation-agnostic qcom,calibration-variant binding to load board-specific calibration data from the device tree. However, the driver never implemented either of these. Given that no devices currently supported use qcom,ath12k-calibration-variant and the previous patch implements qcom,calibration-variant, drop the generation-specific version from the binding to prevent future confusion.
