thermal: samsung: Exynos5260 and Exynos5420 should not use TRIM_RELOAD flag

Currently these SoCs claim TRIM_RELOAD support but don't have
triminfo_ctrl register address defined in their struct
exynos_tmu_registers entries.  This causes incorrect write of
value "1" to data->base + 0x00 address (which happens to be
TRIMINFO register).  Additionally according to the documentation
that I have neither Exynos5260 nor Exynos5420 support/require
TRIM_RELOAD feature.  Thus fix the aforementioned issue by
removing TMU_SUPPORT_TRIM_RELOAD flag for both Exynos5260 and
Exynos5420.
