gpio: pca953x: Fix GPIO resource leak on Intel Galileo Gen 2
[ Upstream commit5.4-rM2-2.2.x-imx-squashed5d8913504c
] When adding a quirk for IRQ on Intel Galileo Gen 2 the commitba8c90c618
("gpio: pca953x: Override IRQ for one of the expanders on Galileo Gen 2") missed GPIO resource release. We can safely do this in the same quirk, since IRQ will be locked by GPIO framework when requested and unlocked on freeing. Fixes:ba8c90c618
