Subject: [PATCH v4 1/2] thermal: mediatek: 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.
