It looks that I have an ordering problem :
 - I want gpio-pxa.probe() to be called at device initcall time

   needs GPIO0 as its interrupt source
   => it might need to honor -EPROBE_DEFER
 - sa1111.sa1111_probe() cannot complete before pxa_cplds_irqs.probe() because
   it needs IRQ305 as its source
   => it might need to honor -EPROBE_DEFER

I wonder if we can work around that by adding this to sa1111_probe():

	if (!irq_get_chip(irq))
		return -EPROBE_DEFER;

It's not particularly nice, but it should at least ensure that things
happen in the right order.
