Pull devfreq updates for v5.13 from Chanwoo Choi:

"1. Update devfreq core

 - Register devfreq as a cooling device when adding devfreq device,
   basically if the flag of devfreq device is set as cooling device.

 - Add missing unlock opeation in devfreq_add_device

 - Use the next frequency as resume_freq instead of previous frequency
   when using opp-suspend property

 - Check whether .get_dev_status in struct devfreq_dev_profile is
   implemented or not by devfreq driver before calling .get_dev_status
   function.

 2. Update devfreq drivers

 - Use dev_err_probe to simplify the error handling on rk3399_dmc.c

 - Remove unused .get_dev_status function on imx8m-ddrc.c because
   imx8m_ddrc_get_dev_status has not returend the any current status
   of the device.

 - Remove unneeded of_match_ptr() from imx-bus.c and imx8m-ddrc.ca

 - Add missing phandle informatioon and replace undefined variable
   with integer value for rk3399_dmc.txt devicetree binding document.

 3. Fix minor issues

 - Fix the wrong set_freq path of userspace governor in
   drivers/devfreq/Kconfig.

 - Remove the invalid description from .get_target_freq in struct
   devfreq_dev_profile."
