cbfs: add cbfs_locate_file()

cbfs_locate_file() can be used to locate the data within the
    cbfs file. Based on the offset and length of the file it can
    then be read into any address without bringing the contents
    into another buffer (platforms without memory-mapped access
    to entire contents of cbfs at once).

BUG=chrome-os-partner:29922
    BRANCH=None
    TEST=Built and booted rush into romstage (stage load still works).
