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

From: Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>

commit cc9432c4fb159a3913e0ce3173b8218cd5bad2e0 upstream.

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 52af318c93e97 ("mmc: Allow
non-sleeping GPIO cd").
