usb: dwc2: Fix HPRT0.PrtSusp bit setting for HiKey 960 board.
commit 5e3bbae8ee3d677a0aa2919dc62b5c60ea01ba61 upstream.
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.")
