mfd: Add pre-regulator device for 88pm860x
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. Signed-off-by: Jett.Zhou <jtzhou@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
