gpio: mpc8xxx: Fix IRQ check in mpc8xxx_probe
platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0);
if (irq < 0)
return irq;
Fix the check of return value to catch errors correctly.
Fixes: 76c47d1449fc ("gpio: mpc8xxx: Add ACPI support")
