Subject: [PATCH v3 1/4] drivers/thermal/exynos: Refactor clk_sec initialization inside SOC-specific case

Refactor the initialization of the clk_sec clock to be inside the
SOC_ARCH_EXYNOS5420_TRIMINFO case. It ensures that the clk_sec clock
is only initialized for the specified SOC and not for other SOCs,
thereby simplifying the code.
