Merge tag 'zxdrm-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into drm-next

ZTE DRM driver updates for 4.11:
 - Add missing selection of VIDEOMODE_HELPERS in Kconfig, since ZTE DRM
   driver uses drm_display_mode_to_videomode().
 - Enable HDMI audio support through SPDIF interface based on generic
   hdmi-audio-codec driver.
 - Enable VOU VL (Video Layer) to support overlay plane with scaling
   function.
 - Refine zx_vou driver a bit and then add TV Encoder output device
   support.

[airlied: fixup plane format change]
