[PATCH] ARM: dt: tegra: cardhu: Add drm components
This patch adds the RGB & HDMI nodes in Tegra 30 cardhu's dts.
This makes the LVDS & HDMI working.
Signed-off-by: Mark Zhang

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 patch enables both LCD (which will always get enabled, since
there's no way to unplug it) and HDMI (which may optionally get enabled,
depending on whether an HDMI device is plugged in). tegradrm currently
has issues when two outputs are enabled at once (and I just validated
this is still true with all the latest patches). As such, please can you
repost with only the internal LCD enabled. We can enable the LCD port
later once the tegradrm issues are fixed. Thanks.
With no HDMI plugged in, I tested Cardhu's LCD and it works fine.
