mfd: Add pre-regulator device for 88pm860x

Browse Source 
Pre-regulator of 88pm8606 is mainly for support charging based on vbus,
it needs to be enabled for charging battery, and will be disabled in
some exception condition like over-temp.
Add the pre-regulator device init data and resource for mfd subdev.
