arm/dt: msm-pm8110: Add VADC and IADC node

Add supported VADC channel nodes to read voltage
from the voltage ADC USR peripheral bank. Clients
can read from supported voltage channels such as
battery voltage, vcoin, usb_in, pmic_therm and
reference channels used for calibration. The IADC
USR peripheral is used to update the offset and
provides an interface to read battery current.
