Yang Li 9f51ce0b9e gpio: mpc8xxx: 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
