kernel: backport mtk_soc_eth fixes from v5.13

Fixes logic that leads to this error when booting mt7621 and other
devices that use the mediatek ethernet driver:
  [   23.144378] mtk_soc_eth 1e100000.ethernet: PPE table busy

The rest are mostly moved from pending-5.10 to backport-5.10 with a
couple of cleanups and improvements from upstream.

Refresh patches.

-Subject: [PATCH] net: ethernet: mtk_eth_soc: fix unnecessary tx queue
- stops
-
-When running short on descriptors, only stop the queue for the netdev that tx
-was attempted for. By the time the something tries to send on the other netdev,
-the ring might have some more room already
