Add backlight and panel nodes for the PAZ00 TFT LCD panel.

This should enable everything needed. Unfortunately, in my tests it only
switches on the backlight, but the display controller blocks in some
infinit loop, so we get no output (and no working system). I post it
here
in case I missed something obvious...

Some users reported that it works when using uboot (yeah, shame on me that I
still use fastboot on my dev machine), so I did a bit more research. It
indeed works when using uboot, even when the display setup is disabled
there. So my guess is that maybe some clock isn't setup by fastboot which
is done by uboot.

ok, to bring this self-conversation to an end, the cpu blocks at a memory 
barrier right after 
	value = tegra_dc_readl(rgb->dc, DC_CMD_DISPLAY_COMMAND);
in tegra_output_rgb_disable (rgb.c).
