octeontx2-af: npc: cn20k: debugfs enhancements
Improve MCAM visibility and field debugging for CN20K NPC.
- Extend "mcam_layout" to show enabled (+) or disabled state per entry
so status can be verified without parsing the full "mcam_entry" dump.
- Add "dstats" debugfs entry: for enabled MCAM indices, print hit deltas
since the prior read by comparing hardware counters to a per-entry
software baseline and advancing that baseline after each read (hardware
counters are not cleared).
- Add "mismatch" debugfs entry: lists MCAM entries that are enabled
but not explicitly allocated, helping diagnose allocation/field issues.
