Subject: [PATCH] usb: dwc3-am62: Disable autosuspend during remove

Runtime PM documentation (Section 5) mentions, during remove()
callbacks, drivers should undo the runtime PM changes done in
probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc. Hence add missing
function to disable autosuspend on dwc3-am62 driver unbind.
