Use a threaded interrupt handler in order to permit the handler to use
a GPIO driver that causes things like I2C transactions being done inside
the handler context.
Also, gpio_keys_init needs to be declared as a late_initcall, to make sure
all needed GPIO drivers have been loaded if the drivers are built into the
kernel.

...which is a horrid hack, but until device dependencies can be
described, it isn't one that can be solved easily.

I really do not want to apply this... Currently the order of
initialization does not matter since nothing actually happens until
corresponding device appears on the bus. Does the OF code creates
devices before all resources are ready?

Thanks.
