This seems to be conflating video support with LCD support. It would be
quite possible to have a board with no LCD, yet supporting display over
HDMI for example. In other words, shouldn't the ifdef above be something
more like:

#if define(CONFIG_LCD_SUPPORT)
	register_lcd_driver();
#endif
#if defined(CONFIG_VIDEO_TEGRA2)
	tegra_display_init(...);
#endif

and internal to tegra_display_init(), the DT is searched for LCD
controller nodes, and if any are found, they're matched to the LCD
driver registered by the first call above.
