usb: mtu3: condition PHY wakeup for host mode and runtime suspend

Browse source

Host bus activity during gadget mode system suspend can trigger
unexpected system wakeups via interrupts because PHY wakeup is enabled
unconditionally.

Improve the suspend flow by conditioning PHY wakeup setup on
device_may_wakeup() and restricting it to host mode or runtime suspend
to ensure proper wakeup handling in gadget mode.
