gpio: sim: mark the GPIO chip as a one that can sleep
commit 5a78d5db9c90c9dc84212f40a5f2687b7cafc8ec upstream.
Simulated chips use a mutex for synchronization in driver callbacks so
they must not be called from interrupt context. Set the can_sleep field
of the GPIO chip to true to force users to only use threaded irqs.
