mfd: qcom-pm8008: Remove workaround for a regmap-irq quirk

Browse Source 
Remove pm8008_init(), which according to the comments exists only
as a workaround for regmap-irq's odd treatment of type registers.
This workaround shouldn't be needed anymore because this driver
uses config registers, which are always programmed by regmap-irq
no matter what the initial register state is.
