It sounds like there's a deeper problem here - if this driver being
deferred, why isn't it being retried after the pinctrl stuff gets
its driver registered?
We've had bugs in this deferred probing before, I wouldn't be surprised
if there's more... and we should not be "fixing" drivers because of bugs
