gpio: mpc8xxx: Prevent NULL pointer deref in demux handler
commit d6de85e85edcc38c9edcde45a0a568818fcddc13 upstream.
commit cfadd838(powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO
driver) added an unconditional call of chip->irq_eoi() to the demux
handler.
This leads to a NULL pointer derefernce on MPC512x platforms which use
this driver as well.
Make it conditional.
