gpio: sim: mark the GPIO chip as a one that can sleep

Browse source

commit 5a78d5db9c 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.
