[RAMEN9610-12194][9610] thermal: exynos_tmu: Add cpu max frequency limit control code.

This patch added thermal driver control to cpu max freqency through temperature.
First if ect has limited_frequency value, exynos-tmu operate limit max frequency to pm qos.
If temperature higher than limited_threshold, driver set max qos to limited_frequency.
And if temperature is lower than limited_threshold_release,
driver release max qos value.
