[PATCH v5 0/3] crypto: KEYS: convert public key to akcipher api

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

This patch set converts the module verification and digital signature
code to the new akcipher API.
RSA implementation has been removed from crypto/asymmetric_keys and the
new API is used for cryptographic primitives.
There is no need for MPI above the akcipher API anymore.
Modules can be verified with software as well as HW RSA implementations.

Patches generated against cryptodev-2.6

Changes in v5:
- Revert back v4 and add a new patch that removes the MPIs from the
  public_key_signature struct after the asymmetric_verify funtc in
  digsig is converted as proposed by Herbert.

Changes in v4:
- Flatten both patches into one to avoid bisect compilation problems.

Changes in v3:
- Don't include keys/asymmetric-type.h in crypto/public_key.h

Changes in v2:
- Fix the whey public_key_signature is setup. The pointer s needs to
  point to the signature instread of the signature_v2_hdr.  
- Select CRYPTO_RSA when INTEGRITY_ASYMMETRIC_KEYS is selected.
