The clocks property has a restriction to maximum one.
Yet, some PHYs may require more than 1 clock such as the IPQ5018 PHY
which requires two clocks for RX and TX. As such, increase maxItems to
two.

Commit 350b7a258f20 introduced the clocks property with a restriction to
maximum 1 to the main ethernet-phy.yaml binding for Realtek to add an
optional external clock source. This is restrictive to all PHY bindings,
as some PHYs may require more than 1 clock such as the IPQ5018 PHY which
requires 2 clocks (for RX and TX).
