FROMGIT: usb: dwc3: qcom: Honor wakeup enabled/disabled state

The dwc3-qcom currently enables wakeup interrupts unconditionally
when suspending, however this should not be done when wakeup is
disabled (e.g. through the sysfs attribute power/wakeup). Only
enable wakeup interrupts when device_may_wakeup() returns true.
