[PATCH 1/2] dt-bindings: phy: mediatek,xsphy: add optional repeater phys property

[Julien Massot <julien.massot@collabora.com>]

USB2 PHY ports may be connected to an external eUSB2 repeater chip.
Add an optional phys property to the port sub-node to allow referencing
it, following the same pattern used by the Synopsys eUSB2 PHY binding.
