On J7 platforms, setting up multiple RX flows was failing as the RX free descriptor ring 0 is shared among all flows and we did not allocate enough elements in the RX free descriptor ring 0 to accommodate for all RX flows. Patch 1 fixes this. The second patch fixes a warning if there was any error in am65_cpsw_nuss_init_rx_chns() and am65_cpsw_nuss_cleanup_rx_chns() was called after that.
