usb: cdns3: Enable workaround for USB2.0 PHY Rx compliance test PHY lockup
USB2.0 PHY hangs in Rx Compliance test when the incoming packet amplitude is varied below and above the Squelch Level of Receiver during the active packet multiple times. Version 1 of the controller allows PHY to be reset when RX fail condition is detected to work around the above issue. This feature is disabled by default and needs to be enabled using a bit from the newly added PHYRST_CFG register. This patch enables the workaround. 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 modes, so we rely on a DT property do decide when to apply the workaround.
