Use a common boardid.h instead of per board copies

There is no point in duplicating boardid.h per board - they are all
    the same. Let's keep a single instance in the common include directory
    and let the linker report a problem if one tries using this function
    on a board where it is not supported.

BUG=chrome-os-partner:30489
    TEST=verified that coreboot builds fine for nyan_big and nyan_blaze.
