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
