usb: dwc2: Fix HPRT0.PrtSusp bit setting for HiKey 960 board.
Increased the waiting timeout for HPRT0.PrtSusp register field
to be set, because on HiKey 960 board HPRT0.PrtSusp wasn't
generated with the existing timeout.
Cc: <stable@vger.kernel.org> # 4.18
Fixes: 22bb5cfdf13a ("usb: dwc2: Fix host exit from hibernation flow.")
