This change is used to remove the port status polling in port reset
functions.
Why it's needed is because:
1) The same polling on same port has taken place prior to this removed
one. See UsbEnumeratePort()->GetPortStatus(). So this polling in
UsbEnumerateNewDev()->ResetPort() is redundant.
2) EDKII Xhci driver hooks all GetPortStatus() operations. If we don't
remove this one, XHCI driver's XhcPollPortStatusChange() may enter twice
in reset process and wrongly think the device is unplugged.

1.Port reset process may not be proper for some vendor's SS hubs. If the corresponding port shows the reset has been done by C_RESET bit we have to skip the whole reset process for attached devices.
2.Clean C_BH_RESET bit immediately to avoid usb timer entering too many times when 5 tiers hubs are connected.
3.Stop checking URB if there is an error happened.
4.Better error handling for fast hot-plug.

1.enlarge the recovery time from 10ms to 20ms after port reset to make set address request success for better device compatibility.
2.another enhancement is to use RESET_C bit rather than RESET bit to judge if hub reset port operation is done.

1) Signal event immediately after HUB UsbRootHubEnumeration event is installed
2) Move UsbHcReset and UsbHcSetState before mUsbRootHubApi.Init
3) Change USB_DEBUG and USB_ERROR to R9 DEBUG macro.
