Subject[PATCH v5 1/2] thermal/drivers/mtk: use function pointer for raw_to_mcelsius
Instead of having if-else logic selecting either raw_to_mcelsius_v1 or
raw_to_mcelsius_v2 in mtk_thermal_bank_temperature introduce a function
pointer raw_to_mcelsius to struct mtk_thermal which is initialized in the
probe function.
