Original change's description:
> Replace drmModeSetCrtc by Atomic APIs
> 
> If the device supports atomic APIs, use drmModeAtomicCommit to modeset
> and disable instead of drmModeSetCrtc.
> Abstracted Modeset and Disabled code to HDPM to handle both atomic and
> legacy call.
> Updated tests to support Connector and CRTC props.
> 
> This is a reland of crrev.com/c/1715751
> 
> BUG=987274

> HardwareDisplayPlaneManagerLegacyTest.Modeset,
> HardwareDisplayPlaneManagerLegacyTest.DisableModeset,
> HardwareDisplayPlaneManagerAtomicTest.DisableModeset, Tested on
> Nautilus(Intel), Grunt(AMD) and Cave(Legacy).
