The raw temperature data was never clamped to SPRD_THM_RAW_DATA_LOW or SPRD_THM_RAW_DATA_HIGH because the return value of clamp() was not used. Fix this by assigning the clamped value to 'rawdata'.

Casting SPRD_THM_RAW_DATA_LOW and SPRD_THM_RAW_DATA_HIGH to u32 is also redundant and can be removed.
