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.
