  PM / devfreq: passive: Fix get_target_freq when not using required-opp (2021-06-24 10:37:35 +0900)

----------------------------------------------------------------
Detailed description for this pull request:

1. Update devfreq core
- Use DEVICE_ATTR_RW macro for devfreq userspace governor

- Add missing error code in devfreq_add_device()

- Fix get_target_freq when not using required-opp

- The 86ad9a24f21e ("PM / devfreq: Add required OPPs support to passive governor")
supported the required-opp property for using devfreq passive governor.
But, 86ad9a24f21e has caused the problem on use-case when required-opp
is not used. So that fix the passive governor for supporting the case of when
required-opp is not used.

2. Update devfreq driver
- Remove unneeded get_dev_status and polling_ms from imx-bus.c because
imx-bus.c doesn't support simple_ondemand.

- Remove unneeded DEVFREQ_GOV_SIMPLE_ONDEMAND dependecy from imx8m-ddrc.c
because it doesn't support simple_ondemand governor.

- Use tegra30-devfreq.c as thermal cooling device
- Convert dt-binding doc style to yaml and add cooling-cells property
information to dt-binding doc for tegra30-devfreq.c
