From: Dekel Peled <dekelp@nvidia.com>

CRYPTO_LOGIN Object is used to login to the device as crypto user
or crypto officer.
Required in order to perform any crypto related control operations.

This patch adds support of CRYPTO_LOGIN object create operation.
Add reading of CRYPTO_LOGIN support capability.
Add function to create general object type CRYPTO_LOGIN, using DevX API.
