usb: cdns3: host: fix endless superspeed hub port reset

commit 9d5333c931347005352d5b8beaa43528c94cfc9c upstream.

When usb 3.0 hub connect with one USB 2.0 device and NO USB 3.0 device,
some usb hub reports endless port reset message.

[  190.324169] usb 2-1: new SuperSpeed USB device number 88 using xhci-hcd
[  190.352834] hub 2-1:1.0: USB hub found
[  190.356995] hub 2-1:1.0: 4 ports detected
[  190.700056] usb 2-1: USB disconnect, device number 88
[  192.472139] usb 2-1: new SuperSpeed USB device number 89 using xhci-hcd
[  192.500820] hub 2-1:1.0: USB hub found
[  192.504977] hub 2-1:1.0: 4 ports detected
[  192.852066] usb 2-1: USB disconnect, device number 89

The reason is the runtime pm state of USB2.0 port is active and
USB 3.0 port is suspend, so parent device is active state.

 cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/usb2/power/runtime_status

 suspended

 cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/usb1/power/runtime_status

 active

 cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/xhci-hcd.1.auto/power/runtime_status

 active

 cat /sys/bus/platform/devices/5b110000.usb/5b130000.usb/power/runtime_status

 active

So xhci_cdns3_suspend_quirk() have not called. U3 configure is not applied.

move U3 configure into host start. Reinit again in resume function in case
controller power lost during suspend.
