This shouldn't be needed at all; devices don't need to declare
themselves as being a pinctrl user in their own compatible flags.

If this change were needed, it should occur before the previous patch to
convert the SPI driver to use pinctrl, so that everything needed by
pinctrl is available in the device tree before the driver attempts to
use it, otherwise someone checking out the code at the previous patch
would find it doesn't work - that will break "git bisect".
