thermal: sprd: Fix temperature clamping in sprd_thm_temp_to_rawdata

The temperature was never clamped to SPRD_THM_TEMP_LOW or SPRD_THM_TEMP_HIGH because the return value of clamp() was not used. Fix this by assigning the clamped value to 'temp'.

Casting SPRD_THM_TEMP_LOW and SPRD_THM_TEMP_HIGH to int is also redundant and can be removed.
