thermal/drivers/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.
