[PATCH 2/2] arm: tegra: ventana: fix display depth, dithering

[Robert Morell <rmorell-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

From: Ari Hirvonen <ahirvonen-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Ventana has a 6-bit-per-component panel, so set the bit depth to 18, and
enable ordered dithering for smoother gradients.

I was going to add this to harmony as well, but harmonay doesn't even have
tegra_dc_out platform data in linux-tegra, so it needs some more love before
this can be added.
