[PATCH v4 0/3] Add exynosautov920 thermal support

This change merges the new exynosautov920-specific register definitions and
timing parameters into the exynos-tmu driver, ensuring consistent behavior
across all Exynos series. All new code paths have been tested on a
exynosautov920 board and verified to correctly read temperatures and
emulate behavior.

Changes in v4:
- Kept 'addtionalProperties: false'.
- Removed the 'samsung,hw-sensor-indices' property in the binding.
- Added the 'samsung,sensors' property in the binding.
- Dropped code-like formatting and rewrote the description in plain,
hardware-focused language in the commit message.
- Removed the bitmap and replaced the tz_count to sensor_count.

Changes in v3:
- Removed redundant commit message.
- Rephrased the sentences to describe the hardware clearly.
- Restricted sensor indices to V920.
- Set #thermal-sensor-cells per variant.
- Replaced 'additionalProperties' with 'unevaluatedProperties'.
- Removed the duplicate #define and use the original.
- Used lowercase hex in #define.
- Simplified 'temp_to_code' and 'code_to_temp' to one computation
path by normalizing calib_temp.

Changes in v2:
- Replace the generic property with a vendor-specific one.
- Added an indices property instead of ranges.
- Shortened thermal node name and made them more generic.
- Updated the indices logic accordingly after removing the ranges property.
