ENGR00292408-2 usb: chipidea: imx: enable different wakeup setting

We have different wakeup setting for different roles:
For peripheral-only mode, we may only enable vbus wakeup.
The Micro-AB cable should not be considered as wakeup source.
For host-only mode, the ID change or vbus change should not be
considered as wakeup source.
For OTG mode, all wakeup setting should be considered as wakeup
source.
