thermal: rockchip: Round up code in rk_tsadcv2_temp_to_code

Browse Source 
rk_tsadcv2_temp_to_code rounds down, so the temperature that triggers the
high temperature interrupt may be lower than the temperature we configured
in dts. Therefore, it may not be possible to update the trip when the high
temperature interrupt occurs, resulting in continuous interruptions.
