I would imagine you either don't need these regmap_del_irq_chip() here
or that you _do_ need them in max77686_i2c_remove().
...from looking at other drivers I think the answer is to add them to
max77686_i2c_remove().

Maybe remove MAX77686_IRQ_NR which no longer makes any sense now that
you start over at 0 partway through.
Overall this looks good to me, so once nits above are fixed feel to
add my Reviewed-by. I've also built and booted this patch on
exynos5250-snow and tested that the RTC wakealarm fires and can even
wake the system up (with some additional work that I'll email you
about).
