[PATCH] dt-bindings: wireless: ath12k: allow calibration variant for WCN7850

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke at toradex.com>

qcom,calibration-variant selects board-specific calibration data for
systems where the bus and device IDs are not unique.

This is not specific to WSI-capable QCN9274 devices. The WSI binding
already allows the property, so allow it in the WCN7850 PCI binding too.

Document qcom,calibration-variant in the WCN7850 PCI binding. The
generic property is already documented for ath12k WSI devices in
qcom,ath12k-wsi.yaml, and selecting board-specific calibration data is
not specific to WSI-capable QCN9274 designs.

This complements Andrew LaMarche's ath12k driver series, which adds
driver support for reading qcom,calibration-variant from the device tree
and drops the deprecated qcom,ath12k-calibration-variant from the WSI
binding:

https://lore.kernel.org/ath12k/20260630133001.1426824-1-andrewjlamarche@gmail.com/T/#t

That series makes the generic property effective in the driver while
this patch closes the schema gap for WCN7850 devices.
