[PATCH v2 1/1] gpio: mxc: use platform_get_irq_optional() to avoid an error message

[Shenwei Wang <shenwei.wang@xxxxxxx>]

From: Fugang Duan <fugang.duan@xxxxxxx>

Use platform_get_irq_optional() to avoid an error message for the
optional irq.

Restructuring the codes to ask for the first mandatory IRQ before
the optional one.

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
