Chunfeng Yun 04284eb74e usb: xhci-mtk: add support runtime PM
A dedicated wakeup irq will be used to handle runtime suspend/resume,
we use dev_pm_set_dedicated_wake_irq API to take care of requesting
and attaching wakeup irq, then the suspend/resume framework will help
to enable/disable wakeup irq.

The runtime PM is default off since some platforms may not support it.
users can enable it via power/control (set "auto") in sysfs.
