Merge branch '2024-03-28-assorted-net-changes' into next

- A few ncsi PHY fixes, clean up PHY GPIO reset code, support LEDs on
  BCM54210E PHY, fix a signed shift overflow in the PHY code, hifemac
  updates, E1000 i225-IT support, improve DM_MDIO+DM_PHY support and
  enable it on the BeaglePlay platform.
