This patch adds IRQ support for the virtio GPIO driver. Note that this
uses the irq_bus_lock/unlock() callbacks, since those operations over
virtio may sleep. Also the notifications for the eventq are processed
using a work item to allow sleep-able operations.

Marc,

Will it be possible for you to have a look at this patch, it will help
us understand shortcomings of the specification better and this
implementation as well.

Thanks.
