ASoC: codecs: pm4125: Remove irq_chip on component unbind

Browse Source 
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.
