[CRYPTO] Use standard byte order macros wherever possible
A lot of crypto code needs to read/write a 32-bit/64-bit words in a specific gender. Many of them open code them by reading/writing one byte at a time. This patch converts all the applicable usages over to use the standard byte order macros. This is based on a previous patch by Denis Vlasenko. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
