crypto: speck - remove Speck

commit 578bdaabd015b9b164842c3e8ace9802f38e7ecc upstream.

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.

@@ -191,21 +191,11 @@ Currently, the following pairs of encryption modes are supported:
 
 - AES-256-XTS for contents and AES-256-CTS-CBC for filenames
 - AES-128-CBC for contents and AES-128-CTS-CBC for filenames
-- Speck128/256-XTS for contents and Speck128/256-CTS-CBC for filenames
 
 It is strongly recommended to use AES-256-XTS for contents encryption.
 AES-128-CBC was added only for low-powered embedded devices with
 crypto accelerators such as CAAM or CESA that do not support XTS.
 
-Similarly, Speck128/256 support was only added for older or low-end
-CPUs which cannot do AES fast enough -- especially ARM CPUs which have
-NEON instructions but not the Cryptography Extensions -- and for which
-it would not otherwise be feasible to use encryption at all.  It is
-not recommended to use Speck on CPUs that have AES instructions.
-Speck support is only available if it has been enabled in the crypto
-API via CONFIG_CRYPTO_SPECK.  Also, on ARM platforms, to get
-acceptable performance CONFIG_CRYPTO_SPECK_NEON must be enabled.
-
 New encryption modes can be added relatively easily, without changes
 to individual filesystems.  However, authenticated encryption (AE)
 modes are not currently supported because of the difficulty of dealing

- * Speck: a lightweight block cipher
- *
- * Copyright (c) 2018 Google, Inc
- *
- * Speck has 10 variants, including 5 block sizes.  For now we only implement
- * the variants Speck128/128, Speck128/192, Speck128/256, Speck64/96, and
- * Speck64/128.   Speck${B}/${K} denotes the variant with a block size of B bits
- * and a key size of K bits.  The Speck128 variants are believed to be the most
- * secure variants, and they use the same block size and key sizes as AES.  The
- * Speck64 variants are less secure, but on 32-bit processors are usually
- * faster.  The remaining variants (Speck32, Speck48, and Speck96) are even less
- * secure and/or not as well suited for implementation on either 32-bit or
- * 64-bit processors, so are omitted.
- *
- * Reference: "The Simon and Speck Families of Lightweight Block Ciphers"
- * https://eprint.iacr.org/2013/404.pdf
- *
- * In a correspondence, the Speck designers have also clarified that the words
- * should be interpreted in little-endian format, and the words should be
- * ordered such that the first word of each block is 'y' rather than 'x', and
- * the first key word (rather than the last) becomes the first round key.
