gpio: wcd934x: mark the GPIO controller as sleeping

[ Upstream commit b5f8aa8d4bde0cf3e4595af5a536da337e5f1c78 ]

The slimbus regmap passed to the GPIO driver down from MFD does not use
fast_io. This means a mutex is used for locking and thus this GPIO chip
must not be used in atomic context. Change the can_sleep switch in
struct gpio_chip to true.
