Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic G12A USB3 + PCIE Combo PHY over to a YAML schemas.

While the original phy bindings specifies phy-supply as required,
the examples and implementations makes it optional, thus phy-supply
is not present in the properties and required lists.

-Required properties:
