This patchset supports for MT8183 chip to mtk_thermal.c.
Add thermal zone of all the thermal sensor in SoC for
another get temperatrue. They don't need to thermal throttle.
And we bind coolers for thermal zone nodes of cpu_thermal.

Changes in v7:  
    - Fix build error in v6. 

Changes in v6:
    - Rebase to kernel-5.11-rc1.
    - [1/3]
	- add interrupts property.
    - [2/3]
	- add the Tested-by in the commit message.
    - [3/3]
	- use the mt->conf->msr[id] instead of conf->msr[id] in the
	  _get_sensor_temp and mtk_thermal_bank_temperature.
	- remove the redundant space in _get_sensor_temp and
	  mtk_read_sensor_temp.
	- change kmalloc to dev_kmalloc in mtk_thermal_probe.

Changes in v5:
    - Rebase to kernel-5.9-rc1.
    - Revise the title of cover letter.
    - Drop "[v4,7/7] thermal: mediatek: use spinlock to protect PTPCORESEL"
    - [2/2]
        -  Add the judgement to the version of raw_to_mcelsius.

Changes in v4:
    - Rebase to kernel-5.6-rc1.
    - [1/7]
        - Squash thermal zone settings in the dtsi from [v3,5/8]
          arm64: dts: mt8183: Increase polling frequency for CPU thermal zone.
        - Remove the property of interrupts and mediatek,hw-reset-temp.
    - [2/7]
        - Correct commit message.
    - [4/7]
        - Change the target temperature to the 80C and change the commit message.
    - [6/7]
        - Adjust newline alignment.
        - Fix the judgement on the return value of registering thermal zone.

Changes in v3:
    - Rebase to kernel-5.5-rc1.
    - [1/8]
        - Update sustainable power of cpu, tzts1~5 and tztsABB.
    - [7/8]
        - Bypass the failure that non cpu_thermal sensor is not find in thermal-zones
          in dts, which is normal for mt8173, so prompt a warning here instead of
          failing.

        Return -EAGAIN instead of -EACCESS on the first read of sensor that
        often are bogus values. This can avoid following warning on boot:

          thermal thermal_zone6: failed to read out thermal zone (-13)

Changes in v2:
    - [1/8]
        - Add the sustainable-power,trips,cooling-maps to the tzts1~tztsABB.
    - [4/8]
        - Add the min opp of cpu throttle.
