[PATCH] ARM: sun8i: sunxi-h3-h5: Prevent merge of external and integrated PHY

[Corentin Labbe]

Actually, some external and integrated PHY are merged due to same dtnode
name "ethernet-phy@1".

This is problematic when we will want to use the phy-is-integrated
property. (Need to delete it on all external PHY node)

An easy solution is to set integrated PHY nodeaddresss at a fake one
that would never be used.
Since board makers currently only provides PHY at addresses 1 and 7,
we will use 31.
