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

stable inclusion
from stable-5.10.68
commit 87479b10eb72f82aa45e8dc6a3dd9bfaec38f9d7
bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=87479b10eb72f82aa45e8dc6a3dd9bfaec38f9d7

--------------------------------

[ Upstream commit a946506c ]

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.
