Some panels (including those on Big DVT) cannot work fine without link training
before sending the video signals, especially multi-lane Full HD panels. We need
to use the fast link training functions from kernel to support them.

Panel datasheet defines some delay between PWM signal out and
backlight enable. This change fixes the current sequence

Panel works fine with dev mode, and the measurement

PLLD, the clock for display, was previously hard-coded to 306MHz. To support
more different panels, we should calcualte PLLD by panel pixel clock
configuration.
Note existing pixel clock configurations for nyan* boards won't work (they used
to rely on hard-coded approximated values) so the device trees are also
modified.

href_to_sync and vref_to_sync are chip specific settings. Currently
they are set to 1/2 of hfront_porch and vfront_porch respectively.
However, to support EDID (CL192730), per David Ung, the safe
values for both are 1 (the same settings as in kernel).

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.

(cherry picked from commit e9d87534ccacb42d508f1902786470798a2dbaea)
nyan: Add a "special-class" for aggregating BCT files into bct.cfg.
The config file which cbootimage processes to create a BCT could come from
multiple different files, individually selected based on config options,
and/or split up into different files for organizational purposes. This change
adds a special-class which collects those files and concatenates them all
together in a bct.cfg which can be processed more easily by other parts of the
build.
While the BCT files themselves are potentially very board specific, for
instance ones that hold memory timing information, this bit of code which
collects them is not. It has to be in each board file instead of alongside the
CPU, however, to ensure that the special class is set up before another
Makefile tries to use it. If we end up with lots of Tegra based boards which
duplicate this code over and over, we might want to revisit how this works.

nyan: Add bct files for nyan.
There's a config option which selects between the emmc and spi config files
depending on what the firmware is intended to boot from. These are copied from
the files installed by the tegra-bct-nyan ebuild, except that the spi config
file has been modified so that there's only one copy of the BCT and so that it
only has one configuration. This is to save space in the final image.
