at86rf230: rework irq_pol setting 



This patch rework the irq_pol register setting for rising and falling
interrupt settings only. The default behaviour should be rising flag.

Also use IRQ_TYPE_* defines instead of IRQF_* defines. There is no
functionality change but irq_get_trigger_type returns IRQ_TYPE_* defines.
