[PATCH v2 1/4] dt-bindings: net: ethernet-phy: move clocks property to invidivual PHY bindings

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

Move the clock property and restriction from the ethernet-phy.yaml file
to the individual PHY binding files. This allows each PHY to manage its
own clock requirements.

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).

There are three other PHY drivers that require clock management:
- Micrel: requires 1 optional clock and the micrel.yaml file already
accomodates for the clock property.
- SMSC: requires an optional clock and the legacy bindings file
(smsc-lan87xx.txt) already accomodates for the clock property.
- BCM7xxx: requires an optional clock. I could not find a bindings file
for this PHY family.
