Put knowledge of task-config dependency in config.h

Rather than have every board check for tasks before declaring their
config macros, have config.h know what configs are invalid without
their corresponding tasks.

BUG=chrome-os-partner:18343
BRANCH=none
TEST=build all platforms and pass unit tests
