gpio: idt3243x: Fix an ignored error return from platform_get_irq()

The return from the call to platform_get_irq() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'irqn', so making 'irqn' an int.

Eliminate the following coccicheck warning:
./drivers/gpio/gpio-mpc8xxx.c:391:5-21: WARNING: Unsigned expression compared with zero: mpc8xxx_gc -> irqn < 0

The return from the call to platform_get_irq() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'parent_irq', so making 'parent_irq' an int.

Eliminate the following coccicheck warning:
