To achieve that with the irq, it used the irq_of_parse_and_map() function when probed in DT-mode, and platform_get_irq() when probed in non-DT mode. This is not necessary: platform_get_irq() works just as fine in DT-mode, since the conversion from DT information to 'struct resource' is done by the generic layers of the kernel. Therefore, this commit switches back to use just platform_get_irq().
