spi: spi-fsl-lpspi: Undo runtime PM changes at driver exit time
[ Upstream commit 3b577de206d52dbde9428664b6d823d35a803d75 ]
It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time unless driver
initially enabled pm_runtime with devm_pm_runtime_enable()
(which handles it for you).
Hence, call pm_runtime_dont_use_autosuspend() at driver exit time
to fix it.
