pinctrl/nomadik: use irq_find_mapping()
The code was using a homegrown method of looking up the offset from the irq domain, not to be encouraged. Use the proper irq_find_mapping() call instead. Cc: Lee Jones <lee.jones@linaro.org> Cc: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
