Use devm_mfd_add_devices() for adding MFD child devices and
devm_regmap_add_irq_chip() for IRQ chip registration.
This patch doesn't include the code regarding devm_mfd_add_devices().
Could you check it again? Or am I missing any previous patches?
This reduces the error code path and .remove callback for removing
MFD child devices and deleting IRQ chip data.
