Merge devfreq updates for v6.12 from Chanwoo Choi:

"Detailed description for this pull request:
 - Add missing MODULE_DESCRIPTION() macros for devfreq governors.
 - Use Use devm_clk_get_enabled() helpers for exyns-bus devfreq driver.
 - Use of_property_present() instead of of_get_property() for imx-bus
   devfreq driver."
