octeontx2-af: Map or unmap NPC MCAM entry and counter

Browse source

Alloc memory to save MCAM 'entry to counter' mapping and since
multiple entries can map to same counter, added counter's reference
count tracking.

Do 'entry to counter' mapping when a entry is being installed
and mbox msg sender requested to configure a counter as well.
Mapping is removed when a entry or counter is being freed or
a explicit mbox msg is received to unmap them.
