From: Lingbo Kong <quic_lingbok@xxxxxxxxxxx>
Pdev id from mac phy capabilities will be sent as a part of
HTT stats request to firmware. This causes issue with single pdev
devices where fimrware does not respond to the stats request
sent from host.
Single pdev devices firmware expects pdev id as 1 for 5GHz/6GHz
phy and 2 for 2GHz band. Handle pdev id for single phy device
while sending HTT stats request message to firmware.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
