The usage of of_device_get_match_data() reduce the code size a bit.
Also, the only way to call mtk_thermal_probe() is to match an entry in
mtk_thermal_of_match[], so of_id cannot be NULL.

MT7622 SoC has built-in thermal controller with one sensing point, the
patch just is to extend the functionality of the existing logic.
Changes v1 -> v2: rebase to 4.16-rc1

The mtk_thermal has some defiens which are never used within the driver.
This patch delets them.

This patch adds support for mt2712 chip to mtk_thermal,
and integrate mt2712 into the same mediatek thermal driver.
MT2712 has only 1 bank and 4 sensors.

If thermal bank with 4 sensors, thermal driver should read TEMP_MSR3.
However, currently thermal driver would not read TEMP_MSR3 since mt8173
thermal driver only use 3 sensors on each thermal bank at the same time,
so this patch would not effect temperature.
Only if mt mt8173 thermal driver use 4 sensors on any thermal bank, would
read third sensor two times, and lose fourth sensor of vale.

This patch adds support for mt2701 chip to mtk_thermal,
and integrate both mt8173 and mt2701 on the same driver.
MT8173 has four banks and five sensors, and MT2701 has
only one bank and three sensors.

This changes the driver to use the devm_ version
of thermal_zone_of_sensor_register and cleans
up the local points and unregister calls.

This adds support for the Mediatek thermal controller found on MT8173
and likely other SoCs.
The controller is a bit special. It does not have its own ADC, instead
it controls the on-SoC AUXADC via AHB bus accesses. For this reason
we need the physical address of the AUXADC. Also it controls a mux
using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.
