Switch 2 has an 88e1545 PHY behind it, which is a quad PHY. Only the
first three PHYs are used, the remaining PHY is unused. When we wire
up the SFF sockets in a later commit, the omission of this causes the
fourth PHY to be used for port 3. Specifying the PHYs in DT avoids
the auto-probing of the bus, and discovery of this PHY.
