hw/net: cadence_gem: Fix MDIO_OP_xxx values

Browse Source 
Testing upstream U-Boot with 'sifive_u' machine we see:

  => dhcp
  ethernet@10090000: PHY present at 0
  Could not get PHY for ethernet@10090000: addr 0
  phy_connect failed

This has been working till QEMU 8.1 but broken since QEMU 8.2.

Fixes: 1b09eeb122 ("hw/net/cadence_gem: use FIELD to describe PHYMNTNC register fields")
