There is no reason to use platform_get_irq() for non-DT probing and
irq_of_parse_and_map() for DT probing. Indeed, platform_get_irq()
works fine for both.
In addition, using platform_get_irq() properly returns -EPROBE_DEFER
when the interrupt controller is not yet available.
Therefore, this commit moves the code filling drv_data->irq outside of
the non-DT vs. DT condition, and simply uses platform_get_irq().
