Subject: [PATCH v2] thermal/drivers/mediatek/lvts_thermal: Remove filtered mode for mt8188

Filtered mode is not supported on mt8188 SoC and is the source of bad
results. Move to immediate mode which provides good temperatures.

Fixes: f4745f546e60 ("thermal/drivers/mediatek/lvts_thermal: Add MT8188 support")

Filtered mode was set by mistake and difficulties with the test setup
prevented from catching this earlier. Use default mode (immediate mode)
instead.

Changes in v2:
- Add the Fixes tag.
- Link to v1: https://lore.kernel.org/r/20240515-mtk-thermal-mt8188-mode-fix-v1-1-e656b310b67f@baylibre.com
