Subject: [PATCH 0/3] Add exynosautov920 thermal support

This patch series adds support for exynosautov920, automotive-grade
processor. Although the exynosautov920's TMU hardware differs slightly
from exisiting platform, its read and calibration logic closely follow
our legacy TMU interface. To prevent runtime and build time errors,
it is kept as a single change rather than being split.

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.
