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.

    (cherry picked from commit 6bbcffe04e8ae73c86bc05c577a67f909857e1c0)

Squashed three commits required to get nyan building since some patches
    were out of order. Added a select to the nyan mainboard Kconfig to have
    a rom size of 1024K to match the saved config on the chromium side.
