Consumer of the kernel crypto api, after allocating
the transformation (tfm), sets the:
- flag 'is_hbk'
- structure 'struct hw_bound_key_info hbk_info'
based on the type of key, the consumer is using.
This helps:
- This helps to influence the core processing logic
for the encapsulated algorithm.
- This flag is set by the consumer after allocating
the tfm and before calling the function crypto_xxx_setkey().
