[OMAPZOOM][PATCH] ISP: Add default white balance values to board file.

[OMAPZOOM][PATCH] ISP: Add default white balance values to board file.

[Dominic Curran]

From: Dominic Curran <dcurran@ti.com>
Subject: [OMAPZOOM][PATCH] ISP: Add default white balance values to board file.

This patch stores the sensors default white balance coefficient values in the 
board file.
This patch keeps the same coef for MT9P012 & OV3640, but changes the coefficients 
for the IMX046.
Changing the coefficients for the IMX046 fixes a yellowish tint in the image.

The patch is based on top of the set of patches labeled 'Component Order'.
