    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.
