[U-Boot,2/2,v2] tegra: enable LCD on PAZ00

This adds LCD panel descriptions to the device tree of PAZ00 and
enables LCD support in the configuration.

I'll create a patch to add LCD support to common TEGRA_DEVICE_SETTINGS
once the tegra tree is rebased.

changes in V2:
	- s/DISPALY/DISPLAY/
	- removed W0 gpio which is not used
	- set all panel-timings to 0
