[PATCH] gpio: mvebu: avoid error message for optional IRQ

[Chris Packham <chris.packham@xxxxxxxxxxxxxxxxxxx>]

platform_get_irq() will generate an error message if the requested irq
is not present

  mvebu-gpio f1010140.gpio: IRQ index 3 not found

use platform_get_irq_optional() to avoid the error message being
generated.
