[PATCH] gpio / ACPI: use *_cansleep version of gpiod_get/set APIs

[Aaron Lu <aaron.lu@xxxxxxxxx>]

The GPIO operation region handler should be called where sleep is
allowed, so we should use the *_cansleep version of gpiod_get/set APIs
or we will get a warning message complaining invalid context if the GPIO
chip has the cansleep flag set.
