usb: host: xhci-plat: add wakeup entry at sysfs

Browse Source 
commit 4bb4fc0dbfa23acab9b762949b91ffd52106fe4b upstream.

With this change, there will be a wakeup entry at /sys/../power/wakeup,
and the user could use this entry to choose whether enable xhci wakeup
features (wake up system from suspend) or not.
