wifi: ath12k: add qmi_cnss_feature_bitmap field to hardware parameters

Currently the CNSS (Connectivity Subsystem) QMI feature is assigned to
qmi_wlanfw_host_cap_req_msg_v01 request directly, this prevents chip-specific
CNSS features from being added easily.

Solve this by adding a new field qmi_cnss_feature_bitmap to hw_params so
chip-specific CNSS features can be assigned to this field and later assigned to
qmi_wlanfw_host_cap_req_msg_v01 request.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
