Make edp display works on chromebook kevin(at least for boot animation).
Also solve some issues i meet during the bringup.
Changes in v5:
Call the destroy hook in the error handling path like in unbind().
Call the destroy hook in the error handling path like in unbind().
Update cleanup order in unbind().
Add disable to unbind(), and inline clk_prepare_enable() with bind().

Let plat drivers own the drvdata, so that they could cleanup resources
in their unbind().
