[PATCH v2] Revert "thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe"

This reverts commit f05c7b7d9ea9477fcc388476c6f4ade8c66d2d26.

That change was causing a regression in the generic-adc-thermal-probed
bootrr test as reported in the kernelci-results list [1].
A proper rework will take longer, so revert it for now.
