video: tegra: cardhu: Default bpp from hardware
This patch adds: 1. A kernel config option that hints to DC driver to use the current value of the color depth register as the default for initializing the FB driver. 2. Checks to see if DC is enabled before reading off the color depth register in tegra_dc_probe.
