ENGR00225131-05 MX6 USB: set stop_mode_config bit if wake up is enabled

IC designer had clarified that 1P1 can be turned off if we do not need support
remote wakeup. So If there is no requirement for USB remote wake up, the 1P1
can be turn off. USB driver will support dynamically turn on(off) 1P1 during
system suspend. 1P1 will be turn on depend on USB wakeup is enabled.

- Set stop_mode_config bit if USB host need support USB remote wake up
- Set stop_mode_config bit if USB device need support USB DP/DM wake
  up system
