In PORTSC, Port Enabled/Disabled(PED) is RW1CS.
When there is a USB device attached on system, current UPWE method
will set 1 to PED, this will cause port disabled as it's RW1CS.
This change is inspired by xhci_port_state_to_neutral in linux driver.
It will mask all RO and RWS bits and set WDE and WCE.
