Rather than having all resource allocation happen in the _bind function
(resulting in possible EPROBE_DEFER returns and component bind/unbind
cycles) allocate and check all resources in _probe function. While we
are at it, use platform_get_irq() to get the IRQ rather than going
through the irq_of_parse_and_map().
