octeontx2-af: npc: cn20k: Allocate npc_priv and dstats dynamically.

Browse source 
Replace the file-scope static npc_priv with a kcalloc'd struct filled
from hardware bank/subbank geometry at init (num_banks is no longer a
const compile-time constant; drop init_done and use a non-NULL
npc_priv pointer for liveness). Thread npc_priv_get() / pointer access
through the CN20K NPC code paths, extend teardown to kfree the root
struct on failure and in npc_cn20k_deinit, and adjust MCAM section
setup to use the discovered subbank count.

Allocate MCAM debugfs dstats via devm_kzalloc instead of a static matrix,
and use the allocated backing store consistently when computing deltas
(including the counter rollover compare).
