This patch is a modification related to masking of the temp_error value
in the sanitize_temp_error() function.
For SOC_ARCH_EXYNOS7, the temp_error1, 2 value should be masked as
EXYNOS7_TMU_TEMP_MASK(0x1ff).
The current code masks temp_error2 with EXYNOS_TMU_TEMP_MASK(0xff)
value even in the case of EXYNOS7.
In addition, when entering the if statement, both temp_error1 and 2
are masked with EXYNOS_TMU_TEMP_MASK(0xff).
By modifying to use the previously declared local variable tmu_temp_mask,
the mask value suitable for the SOC can be applied.
