It's a very old driver with a lot of potential for cleaning up code to
modern standards. This was a simple one dealing with mostly the probe
function and adding some devm to it.

All patches were tested on a Cisco Meraki MX60W. Boot and
Shutdown/Reboot showed no warnings.

  net: ibm: emac: manage emac_irq with devm
  net: ibm: emac: use devm for of_iomap
  net: ibm: emac: remove mii_bus with devm
  net: ibm: emac: use devm for register_netdev
  net: ibm: emac: use netdev's phydev directly

This is a 12 year old PowerPC system. Cool you found one. Looks like
OpenWRT still supports it.

I recently bought one in an attempt to get qca8k working on it.
Unfortunately the bootloader disables all ports except WAN and the
driver has a hack that disables MDIO 0-3, which qca8k seems to need. I
tried removing it but then mdiobus_alloc fails with error code -5.

qca8k only manages to bring up port 5 (WAN).
