[PATCH v4 0/3] crypto: akcipher - Changes to asymmetric key API

[Tadeusz Struk <tadeusz.struk@intel.com>]

This series updates the asymmetric key API.
The changes include
 - setkey function has been split into set_priv_key and set_pub_key.
 - akcipher requests takes sgl for src and dst instead of void *.
Users of the API i.e. two existing RSA implementation and
test mgr code have been updated accordingly.

First patch adds sg_len helper that returns the full length
of an sgl.
Second patch adds sgl helpers to mpi library.
Third patch implements the API changes in rsa-generic and rsa-qat

Changes in v4:
- add back src_len and dst_len
- add sgl helpers to mpi library
- change rsa-generic implementation to use the new mpi helpers

Changes in v3:
- changed type returned from sg_len from int to unsigned int

Changes in v2:
- dropped patches that checked value returned by crypto_unregister_alg
- flatten patches 4 and 6-8 from v1 into one patch.
