[PATCH v2 2/3] dt-bindings: usb: cdns,usb3: Add cdns,phyrst-a-enable property

Controller version 0x0002450D has USB2 PHY RX sensitivity issues that needs to be worked around by enabling phyrst-a-enable bit in PHYRST_CFG register. There is no way to know controller version before device controller is started and the workaround needs to be applied for both host and device
