gpio: pca953x: Fix direction setting when configure an IRQ
The commit 0f25fda840a9 ("gpio: pca953x: Zap ad-hoc reg_direction cache")
seems inadvertently made a typo in pca953x_irq_bus_sync_unlock().
When the direction bit is 1 it means input, and the piece of code in question
was looking for output ones that should be turned to inputs.
Fix direction setting when configure an IRQ by injecting a bitmap complement
operation.
Fixes: 0f25fda840a9 ("gpio: pca953x: Zap ad-hoc reg_direction cache")
Depends-on: 35d13d94893f ("gpio: pca953x: convert to use bitmap API")
