mmc: slot-gpio: Allow non-sleeping GPIO ro 



This change uses the appropriate _cansleep or non-sleeping API for
reading GPIO read-only state. This allows users with GPIOs that
never sleepbeing called in atomic context.

Implement the same mechanism as in commit 52af318c ("mmc: Allow
non-sleeping GPIO cd").
