Subject: [PATCH v3 2/2] thermal: mediatek: change clk_prepare_enable to devm_clk_get_enabled in mtk_thermal_probe

use devm_clk_get_enabled to do automatic resource management.
Meanwhile, remove error handling labels in the probe function and
the whole remove function.

v3 -> v2: remove some useles func calls.
v2 -> v1: init

Notice the devm_clk_get_enabled do the clk_get and clk_prepare_enable
at the same time.
I'm not sure if this has any side effects in initialization.
