[PATCH 0/9] PM / devfreq: Remove deprecated 'devfreq' and 'devfreq-events' properties

The devfreq and devfreq-event subsystem provided the following two properties:
- Provide 'devfreq' property in order to get the parent devfreq device
by devfreq_get_devfreq_by_phandle() if devfreq device use passive governor.
- Provide 'devfreq-events' property in order to get the devfreq-event device
by devfreq_event_get_edev_by_phandle().

But, two properties name is not proper expressing the h/w
and 'devfreq' word is name of linux subsystem intead of any h/w name.

Hand over the rights for deciding the property name for getting
the devfreq/devfreq-event device on devicetree, to each devfreq driver.

So, replace 'devfreq' and 'devfreq-events' property with following property
name according to each devfreq driver:
--------------------------------------------------------------------
Old property | New propert | Device driver name |
--------------------------------------------------------------------
devfreq | exynos,parent-bus | exynos-bus.c |
| | |
devfreq-events| exynos,ppmu-device | exynos-bus.c, exynos5422-dmc.c|
| rockchip,dfi-device| rk3399_dmc.c |
--------------------------------------------------------------------
