[PATCH v5 0/3] thermal: mediatek: Add LVTS architecture thermal controller

This patch move thermal files related to Mediatek to the mediatek folder.
And introduce the new architecture LVTS (low pressure thermal sensor) driver to report
the highest temperature in the SoC and record the highest temperature sensor,
each sensor as a hot zone.
The LVTS body is divided into two parts, the LVTS controller and the LVTS device.
The LVTS controller can connect up to 4 LVTS devices, and each LVTS device
can connect up to 7 TSMCUs.

The architecture will be the first to be used on mt6873 and mt8192.

Change in v5:
        - Use 'git mv' for the relocated file.

Change in v4:
        - Rebase to kernel-v5.13-rc1
        - Resend

Change in v3:
        - [2/3]
          - change the expression in the lvts_temp_to_raw to dev_s64.

Change in v2:
        - Rebase to kernel-5.11-rc1.
        - [2/3]
          - sort headers
          - remove initial value 0 of msr_raw in the lvts_temp_to_raw.
          - disconstruct the api of lvts_read_tc_msr_raw.
          - add the initial value max_temp = 0 and compare e.q.
            in the lvts_read_all_tc_temperature.
          - add the return with invalid number in the lvts_init.

This patch depends on [1].
