MT8365 is similar to the other SoCs supported by the driver. It has only
one bank and 3 actual sensors that can be multiplexed. There is another
one sensor that does not have usable data.

Add logic in order to be able to turn on the control buffer on MT8365.
This change now allows to have control buffer support for MTK_THERMAL_V1,
and it allows to define the register offset, and mask used to enable it.

Replace the accesses to 'tz->type' by its accessor version in order to
self-encapsulate the thermal_zone_device structure.

Some drivers are directly using the thermal zone's 'device' structure
field.
Use the driver device pointer instead of the thermal zone device when
it is available.
Remove the traces when they are duplicate with the traces in the core
code.

The devres variant of thermal_add_hwmon_sysfs() only takes the thermal
zone structure pointer as parameter.
Actually, it uses the tz->device to add it in the devres list.
It is preferable to use the device registering the thermal zone
instead of the thermal zone device itself. That prevents the driver
accessing the thermal zone structure internals and it is from my POV
more correct regarding how devm_ is used.

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

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.

Add MediaTek proprietary folder to upstream more thermal zone and cooler
drivers, relocate the original thermal controller driver to it, and rename it
as "auxadc_thermal.c" to show its purpose more clearly.
