Changes:
- This patch depcrates the patch:
  "[PATCH V2] ARM: dt: tegra: cardhu: Add drm components"
  Because the issue that LCD and HDMI can't work at the same time
  has been fixed by Thierry's patch:
  "drm: tegra: Use framebuffer pitch as line stride"

This still doesn't add any of the backlight/panel GPIO programming,
which I believe is required before we enable any LCDs. We could add the
HDMI node without that though.

Okay. So I think I may misunderstood your words several days ago, when I
submitted the v1 and v2 version for this patch.

So let's hold on this and wait for the backlight/panel working on cardhu.
