mb/google/geralt: Increase VM18 LDO voltage to 1.9V for Ciri
The current panel voltage measured at mainboard side is 1.79V and the
voltage at panel side is 1.74V. Since the panel requires 1.8V or more,
increase the circuit voltage to 1.9V to meet the panel requirement.
After adjustment mainboard side voltage is 1.89V and panel side is
1.84V.
