net: ethernet: mtk_eth_soc: Fix DIM support for MT7628/88
When updating to latest mainline for some testing on the GARDENA smart gateway based on the MT7628, I noticed that ethernet does not work any more. Commit e9229ffd550b ("net: ethernet: mtk_eth_soc: implement dynamic interrupt moderation") introduced this problem, as it missed the RX_DIM & TX_DIM configuration for this SoC variant. This patch fixes this by calling mtk_dim_rx() & mtk_dim_tx() in this case as well.
