spi: cadence: fix unclocked access on unbind

commit 5b1689a41f02955c5361944f748a4812a6ff9307 upstream.

Make sure that the controller is runtime resumed before disabling it
during driver unbind to avoid unclocked register access and unbalanced
clock disable.

Also restore the autosuspend setting.

This issue was flagged by Sashiko when reviewing a controller
deregistration fix.
