If you say yes to this option, support will be included for the
built-in PM8xxx PMIC chips.

This is required if your board has a PM8xxx and uses its features,
such as: MPPs, GPIOs, regulators, interrupts, and PWM.

Say M here if you want to include support for PM8xxx chips as a
module. This will build a module called "pm8xxx-core".
