[PATCH ath-next 1/9] wifi: ath12k: introduce ath12k_fw_feature_supported()

[Baochen Qiang]

There are several places checking if a specific bit set in
ab->fw.fw_features, and in an upcoming patch additional check needs to be
added at all places.

Introduce a new helper ath12k_fw_feature_supported() to avoid code
duplication.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00209-QCAHKSWPL_SILICONZ-1
