qcacmn: Allow FW to pno scan 6G chan based on RNR flag only

First host checks below two things in PNO scan request:
1. Userspace sets NL80211_SCAN_FLAG_COLOCATED_6GHZ flag
in pno scan request.
2. At least one 6G channel is present in the pno scan req.

If any of above conditions satisfy, Host fills all remaining
(other than channel(s) present in pno scan req) valid 6 GHz
channel(s) to pno scan requests and set the flag
FLAG_SCAN_ONLY_IF_RNR_FOUND for each remaining channel(s).
Host sends this updated channel list via WMI command
WMI_START_SCAN_CMDID_param_tlvs->channel_list for pno scan
to firmware.

By this driver allows Firmware to scan 6G channels based on
RNR IEs only (for colocated APs reported by 2.4/5 GHz APs).
