octeontx2-pf: cn10K: Reserve LMTST lines per core
This patch reserves the LMTST lines per cpu instead of separate LMTST lines for NPA(buffer free) and NIX(sqe flush). LMTST line of the core on which SQ or RQ is processed is used for LMTST operation. This patch also replace STEOR with STEORL release semantics and updates driver name in ethtool file.
