at86rf230: add irq low-level for polarity
The at86rf2xx chips supports the setting of irq polarity if active low or active high. This patch adds a handling for IRQ_ACTIVE_LOW if the irq_type is IRQ_TYPE_LEVEL_LOW. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
