usb: dwc3-am62: Disable autosuspend during remove 

stable inclusion
from stable-v6.6.72
commit 7c3f7c3caa35c733f6a1ccdaa02c4051dc48c471
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBQN9L

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=7c3f7c3caa35c733f6a1ccdaa02c4051dc48c471



--------------------------------

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.
