qcacld-3.0: Add PTP timestamp socket options RX support

Host need to fill netbuf with qtime instead of tsf. So host first
need to set enable_ppdu_end to 1, so that FW will pass ppdu_end
contents to host, and host can translate tsf64_time into qtime.
The tsf64_time is new added to fw struture, so host will need
add it accordingly to struct hdd_adapter, and keep it updated
in time synchronization function <hdd_update_timestamp>.
