thermal/drivers/hisi: Move the clk setup in the corresponding functions
The sensor's clock is enabled and disabled outside of the probe and disable function. Moving the corresponding action in the hisi_thermal_setup() and hisi_thermal_disable_sensor(), factors out some lines of code and makes the code more symmetric.
