Extend the low level ep11 misc functions implementation by
several functions to support EP11 key objects for paes and pkey:
- EP11 AES secure key generation
- EP11 AES secure key generation from given clear key value
- EP11 AES secure key blob check
- findcard function returns list of apqns based on given criterias
- EP11 AES secure key derive to CPACF protected key
Extend the pkey module to be able to generate and handle EP11
secure keys and also use them as base for deriving protected
keys for CPACF usage. These ioctls are extended to support
EP11 keys: PKEY_GENSECK2, PKEY_CLR2SECK2, PKEY_VERIFYKEY2,
PKEY_APQNS4K, PKEY_APQNS4KT, PKEY_KBLOB2PROTK2.
Additionally the 'clear key' token to protected key now uses
an EP11 card if the other ways (via PCKMO, via CCA) fail.
The PAES cipher implementation needed a new upper limit for
the max key size, but is now also working with EP11 keys.

This patch introduces two new files which provide some
low level functions to interact with EP11 crypto cards:
ep11_get_card_info() sends an EP11 query module info CPRB to the
addressed card, processes the returning reply and exposes some of
the information returned in the new ep11_card_info struct.
ep11_get_domain_info() sends an EP11 query domain info CPRB to the
addressed card/queue, processes the returning reply and exposes some
of the information returned in the new ep11_domain_info struct.
