Subject: [PATCH 2/5] dt-bindings: wireless: ath11k: Strip ath11k prefix
 from calibration property

Devicetree properties describing exactly the same thing should be
reusable between device bindings.  All Qualcomm Atheros WiFi chips needs
certain calibration data, so properties should not be prefixed with
device family (ath11k).

Deprecate qcom,ath11k-calibration-variant and alike, so we gradually
switch to a common property.  This will also allow moving these
properties to common schema, if desired.
