Johan Hovold 25f11ed965 greybus: gpio: fix atomic sleep when using interrupts 
The irq-chip callbacks are made in atomic context where we must not do
any synchronous greybus operations.

Fix the current gpio-interrupt implementation by using the bus-lock
functionality provided by the irq subsystem.
