[PATCH v1 1/1] pinctrl: iproc: Use platform_get_irq_optional() to avoid error message

[Rayagonda Kokatanur <rayagonda.kokatanur@xxxxxxxxxxxx>]

Use platform_get_irq_optional() instead of platform_get_irq() to avoid
below error message during probe:

[ 0.589121] iproc-gpio 66424800.gpio: IRQ index 0 not found
