    crypto: cryptd - Use subsys_initcall to prevent races with aesni
    
    As cryptd is depeneded on by other algorithms such as aesni-intel,
    it needs to be registered before them.  When everything is built
    as modules, this occurs naturally.  However, for this to work when
    they are built-in, we need to use subsys_initcall in cryptd.
