This is going to break any system where we use both a GPIO chip select and chip select 0. Ideally we'd try to figure out an unused chip select to use here...
The point is that this use case is already broken and this patch fixes the crash and is easily backportable.
Fixing the CS + gpio CS should probably be done in a separate patch.
If the GPIO is overlaid on any of the existing slots (except GPIO 0) then it'll cause GPIO 0 to start toggling. I'm not convinced that the code doesn't currently support that.
