[PATCH v5 3/3] drivers/thermal/exymos: Fixed the efuse min max value for exynos5422

[Anand Moon <linux.amoon@gmail.com>]

As per Exynos5422 user manual e-Fuse range min~max range is 16~76.
if e-Fuse value is out of this range, then thermal sensor may not
sense thermal data properly. Refactors the efuse value
initialization logic within exynos_map_dt_data function by
replacing the nested if-else statements with a switch statement.
Ensures proper initialization of efuse values based on the SOC type.
