Subject: [net-next PATCH 09/11] octeontx2-af: Accommodate more bandwidth profiles for cn20k

CN20K has 16k of leaf profiles, 2k of middle profiles and
256 of top profiles. This patch modifies existing receive
queue and bandwidth profile context structures to accommodate
additional profiles of cn20k.
