Subject: [PATCH 02/18] octeontx2-af: Add NPA aura and pool contexts to debugfs

From: Christina Jacob <cjacob@...vell.com>

To aid in debugging NPA related issues, added support to dump
NPA (pool allocator) block LF's aura and pool hardware contexts in
debugfs. User can check which contexts are enabled currently and dump
it's current HW context.

Three new files 'qsize', 'aura_ctx', 'pool_ctx' are added to the
debugfs at 'sys/kernel/debug/octeontx2/npa/'

'echo <npalf index> > qsize' will display current enabled Aura/Pools.
'echo <npalf> [aura number/all] > aura_ctx' &
'echo <npalf> [aura number/all] > pool_ctx' will dump Aura/Pool
context info.
