t124: Clean up display init functions

Browse source 
The existing display init functions were translated from a script. The new
code will play the same functions but are cleaner and readable and easier to
be ported to new panel.

BUG=none
TEST=build nyan and boot up kernel.

Squashed to pass abuild

nyan: Fix the build for big and blaze.

The display code for the tegra124 was cleaned up recently, but only the nyan
device tree was updated to match the new code, not big's or blaze's. This
change copies nyan's device tree over to those other two boards which will get
them building again. The settings may not be correct, but they'll be no less
correct than they were before. I also updated the copyright date for nyan.

BUG=none
TEST=Built for nyan, nyan_big, nyan_blaze. Booted on nyan_big and verified the
panel wasn't damaged by the new display code or settings.
BRANCH=None
