  PM / devfreq: imx8m-ddrc: Remove unneeded of_match_ptr() (2021-04-08 13:14:51 +0900)

----------------------------------------------------------------
Detailed description for this pull request:
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 driver
- 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
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. Update minor issue
- 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
