crypto: speck - remove Speck

These are unused, undesired, and have never actually been used by
anybody. The original authors of this code have changed their mind about
its inclusion. While originally proposed for disk encryption on low-end
devices, the idea was discarded [1] in favor of something else before
that could really get going. Therefore, this patch removes Speck.

Speck is a lightweight block cipher that is tuned for optimal
performance in software (rather than hardware).
Speck may not be as secure as AES, and should only be used on systems
where AES is not fast enough.
