Kaka Ni has uploaded this change for review.
WIP: google/kukui: elaborate panel support for Kukui family boards.
There are two boards based on Kukui: Flapjack & Krane.
Now the edid inf and init commands for panels of Kukui are in
mainbard.c.
This CL would elabrate panel support for Kukui family. Each board has
it's own source file to support it's panels.
BUG=Nne
BRANCH=none
TEST=build pass
