mfd: da9055: Fix missing regmap_del_irq_chip() in error path

Browse Source 
[ Upstream commit 1b58acfd067ca16116b9234cd6b2d30cc8ab7502 ]

When da9055_device_init() fails after regmap_add_irq_chip()
succeeds but mfd_add_devices() fails, the error handling path
only calls mfd_remove_devices() but forgets to call
regmap_del_irq_chip(). This results in a resource leak.

Fix this by adding regmap_del_irq_chip() to the error path so
that resources are released properly.
