spi: atmel-quadspi: Undo runtime PM changes at driver exit time

[ Upstream commit 438efb23f9581659495b85f1f6c7d5946200660c ]

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.
