usb: ohci-da8xx: disable controller wakeup on cleanup

Browse source

The OHCI core marks controllers with RemoteWakeupConnected as
wakeup-capable. Probe enables wakeup, but neither removal nor a later
notifier registration failure disables it, leaving the wakeup source
attached.

Disable controller wakeup after removing the HCD on both paths.

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
