octeontx2-af: Add NIX Errata workaround on CN10K silicon
This patch adds workaround for below 2 HW erratas
1. Due to improper clock gating, NIXRX may free the same
NPA buffer multiple times.. to avoid this, always enable
NIX RX conditional clock.
2. NIX FIFO does not get initialized on reset, if the SMQ
flush is triggered before the first packet is processed, it
will lead to undefined state. The workaround to perform SMQ
flush only if packet count is non-zero in MDQ.
