thermal: exynos: remove needless triminfo_ctrl abstraction
reg->triminfo_ctrl[] is used in only exynos_tmu_initialize() and
accessed only if TMU_SUPPORT_TRIM_RELOAD flag is set. This flag
is set only on Exynos3250, Exynos4412 and Exynos5250 (other SoC
types don't even have triminfo_ctrl[] entries assigned in their
struct exynos_tmu_registers instances) so the register abstraction
is not needed and can be removed.
There should be no functional changes caused by this patch.
