If platform_get_irq() returns IRQ0 (considered invalid according to Linus)
the driver blithely passes it to ata_host_activate() that treats IRQ0 as
a sign that libata should use polling and thus complains about non-NULL
IRQ handler passed to it. Deny IRQ0 right away, returning -EINVAL from
the probe() method...
