[AVR32] extint: Set initial irq type to low level
David Brownell pointed out a mismatch in the avr32 extint code: > I noticed a small glitch that's not fixed by this patch: the > initial type is falling edge, but IRQ_TYPE_NONE is mapped to > IRQ_TYPE_LEVEL_LOW. Potentially surprising. Fix it by setting the initial type (and handler) to low level, matching the meaning of IRQ_TYPE_NONE. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
