net: bcmgenet: fix OF node of MII bus controller

The bcmgenet device tree binding describes the MDIO controller as a
subnode of the Ethernet controller node. Linux handles this by having
a driver for each of the MAC and MDIO controller, but in barebox we
keep a single driver and largely ignore the subnode.

Since Commit 8abc2059298d ("net: add support for MDIO devices"), this
leads to following error message:

  ERROR: miibus0: /scb/ethernet@7d580000/mdio@e14 PHY address 3604 is too
  large

Give the MII bus the correct device tree node to fix this. We already do
it this way in the designware_eqos driver.

This was tested on a Raspberry Pi 4b, where Link up and reading PHY ID
of 600d 84a2 is sensible (matches PHY_ID_BCM54210E). DHCP though didn't
work for me with or without this patch.
