Re: [PATCH 4/9] PM / devfreq: exynos-bus: Replace deprecated 'devfreq' property

In order to remove the deprecated 'devfreq' property, replace with
new 'exynos,parent-bus' property in order to get the parent devfreq device
in devicetree file instead of 'devfreq' property. But, to guarantee the
backward-compatibility, keep the support 'devfreq' property.
