From: Prashanth K <quic_prashk@xxxxxxxxxxx>
commit 625e70ccb7bbbb2cc912e23c63390946170c085c upstream.
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.
