qcacmn: Move packet log to HTT

Packet log messages be coming as HTT messages for Lithium. Temporary
change to bypass HTC connection for this new HIF pipe (CE 5), which
will be used for packet log and other high-priority HTT messsages.
Proper HTC connection to be added later once required FW changes
are available
