Octeontx2-af: Fetch MAC channel info from firmware

Browse source 
Packet ingress and egress MAC/serdes channel numbers are configurable
on CN10K series of silicons. These channel numbers inturn used while
installing MCAM rules to match ingress/egress port. Fetch these channel
numbers from firmware at driver init time.
