571c47ab98 crypto: chelsio - replace AES cipher calls with library calls
Replace a couple of occurrences where the "aes-generic" cipher is
instantiated explicitly and only used for encryption of a single block.
Use AES library calls instead.

d6be72ee2c crypto: chtls - use 64-bit arithmetic instead of 32-bit
Cast *val* to u64 in order to give the compiler complete
information about the proper arithmetic to use.

Notice that such variable is used in a context that expects an
expression of type u64 (64 bits, unsigned) and the following
expression is currently being evaluated using 32-bit arithmetic:

val << bit_pos
