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.
