The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream. IRQ0 is no longer returned by platform_get_irq(),
so we now can safely ignore it...
