gpio: pxa: Avoid a warning when gpio0 and gpio1 IRQS are not there

Not all platforms use those. Let's use platform_get_irq_byname_optional() instead platform_get_irq_byname() so that we avoid a useless warning: [ 1.359455] pxa-gpio d4019000.gpio: IRQ gpio0 not found [ 1.359583] pxa-gpio d4019000.gpio: IRQ gpio1 not found Signed-off-by: Lubomir Rintel <[email protected]> Signed-off-by: Bartosz Golaszewski <[email protected]>
