From: Bin Meng <bm...@tinylab.org>
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: 1b09eeb122aa ("hw/net/cadence_gem: use FIELD to describe PHYMNTNC
register fields")
