octeontx2-af: Fix CGX Receive counters
[ Upstream commit bf449f35e77fd44017abf991fac1f9ab7705bbe0 ]
Each CGX block supports 4 logical MACs (LMACS). Receive
counters CGX_CMR_RX_STAT0-8 are per LMAC and CGX_CMR_RX_STAT9-12
are per CGX.
Due a bug in previous patch, stale Per CGX counters values observed.
