Use platform_irq_get() instead platform_get_resource() for IRQ resource
to fix the probe failure. platform_get_resource() fails to fetch the IRQ
resource as it might not be ready at that time.

platform_irq_get() is also the recommended way to get interrupt as it
directly gives the IRQ number and no conversion from resource is
required.
