qcacld-3.0: Handle ACS freq list zero
When all chan in ACS freq list is filtered out
by wlan_hdd_trim_acs_channel_list, the hostapd start will
fail. This happens when PCL is PM_24G_SCC_CH_SBS_CH,
and SAP acs range includes 5G channel list.
One example is STA active on 6Ghz chan. Hostapd start
SAP on 5G ACS range. The intersection of PCL and ACS range
is zero.
Instead of ACS failure, add API wlan_hdd_handel_zero_acs_list
to select one channel from ACS range and report to Hostapd.
When hostapd "start_ap", the driver will force SCC to 6G
or move SAP to 2G based on SAP's configuration.
