i.MX: Add FIQ support
Drivers which are going to use it will have to select it and use imx_set_irq_fiq() to set FIQ mode for this interrupt. Changes since V1: - removed '#ifdef CONFIG_FIQ' from irqs.h - renamed imx_set_irq_type() to imx_set_irq_fiq() - made irqt unsigned - fixed irq number check Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
