wifi: ath11k: Set ext passive scan flag to adjust passive scan start time
Set the WMI_SCAN_FLAG_EXT_PASSIVE_SCAN_START_TIME_ENHANCE flag
while sending the scan command. If this flag is enabled when the
incoming scan request comes with a strict start time and its duration
overlaps with next TBTT, then target adjust the start time accordingly
for passive scan. Target supporting this feature will advertise
WMI_TLV_SERVICE_PASSIVE_SCAN_START_TIME_ENHANCE.
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01467-QCAHKSWPL_SILICONZ-1
