wifi: ath11k: Send 11d scan start before WMI_START_SCAN_CMDID

Firmwares advertising the support of triggering 11d algorithm on the
scan results of a regular scan expects driver to send
WMI_11D_SCAN_START_CMDID before sending WMI_START_SCAN_CMDID.
Triggering 11d algorithm on the scan results of a normal scan helps
in completely avoiding a separate 11d scan for determining regdomain.
This indirectly helps in speeding up connections on station
interfaces on the chipsets supporting 11D scan.

To enable this feature, send WMI_11D_SCAN_START_CMDID just before
sending WMI_START_SCAN_CMDID if the firmware advertises
WMI_TLV_SERVICE_SUPPORT_11D_FOR_HOST_SCAN service flag.

WCN6750 & WCN6855 supports this feature.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-01160-QCAMSLSWPLZ-1
Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
