mfd: tqmx86: Clear GPIO IRQ resource when no IRQ is set

Browse source 
[ Upstream commit a946506c48f3bd09363c9d2b0a178e55733bcbb6 ]

The driver was registering IRQ 0 when no IRQ was set. This leads to
warnings with newer kernels.

Clear the resource flags, so no resource is registered at all in this
case.
