    cpuidle is currently optional, that is why the two level hierarchy
    is there so that you can still have simple idle selection without it.

    % size drivers/cpuidle/*.o
    text data bss dec hex filename
    5514 1416 44 6974 1b3e drivers/cpuidle/built-in.o

    Adding it unconditionally would add ~7k to everyone who wants idle functions.

    I think making it unconditional would require putting it on a serious
    diet first.
