Component bind uses devm_regmap_add_irq_chip() to add IRQ chip, so it will be removed only during driver unbind, not component unbind. A component unbind-bind cycle for the same Linux device lifetime would result in two chips added. Fix this by manually removing the IRQ chip during component unbind.
