Balsam CHIHI f5f633b182 thermal/drivers/mediatek: Add the Low Voltage Thermal Sensor driver 
The Low Voltage Thermal Sensor (LVTS) is a multiple sensors, multi
controllers contained in a thermal domain.

A thermal domains can be the MCU or the AP.

Each thermal domains contain up to seven controllers, each thermal
controller handle up to four thermal sensors.

The LVTS has two Finite State Machines (FSM), one to handle the
functionin temperatures range like hot or cold temperature and another
one to handle monitoring trip point. The FSM notifies via interrupts
when a trip point is crossed.

The interrupt is managed at the thermal controller level, so when an
interrupt occurs, the driver has to find out which sensor triggered
such an interrupt.

The sampling of the thermal can be filtered or immediate. For the
former, the LVTS measures several points and applies a low pass
filter.
