spi: zynqmp-gqspi: Undo runtime PM changes at driver exit time​

[ Upstream commit 2219576883e709737f3100aa9ded84976be49bd7 ]

It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time.

So, call pm_runtime_dont_use_autosuspend() at driver exit time
to fix it.
