From: Arend Van Spriel <arend.vanspr...@broadcom.com>
Add support to handle scheduled scan request containing BSSID in
the matchsets. The firmware can send event upon finding BSSIDs and
SSIDs. To get these in one event the bit REPORT_SEPARATELY needed
to be removed from the flags in brcmf_pno_config().
