Linus Walleij e9bdf7e655 gpio: fix locking open drain IRQ lines 
We provided the right semantics on open drain lines being
by definition output but incidentally the irq set up function
would only allow IRQs on lines that were "not output".

Fix the semantics to allow output open drain lines to be used
for IRQs.
