spi: fix explicit controller deregistration
Johan Hovold <johan@kernel.org> says:
Turns out we have a few drivers that get the tear down ordering wrong
also when not using device managed registration (cf. [1] and [2]).
Fix this to avoid issues like system errors due to unclocked accesses,
NULL-pointer dereferences, hangs or failed I/O during during
deregistration (e.g. when powering down devices).
