usb: dwc3: xilinx: fix usb3 non-wakeup source resume failure

When USB is in super-speed mode and disabled as a wakeup source,
observed that on the resume path, lanes have not been configured
properly in the phy-zynqmp driver.
As a result, after the resume, USB device detection failed on host.

To resolved the above issue, added phy_init on resume and phy_exit
on suspend path, to configure the GT lanes correctly.
The re-initialization of phy, reset the device and re-enumerate
the USB subsystem.

This use-case is specific to Xilinx ZynqMP SoC.
