s390/crypto: Add hardware acceleration for full AES-XTS mode

Extend the existing paes cipher to exploit the full AES-XTS hardware
acceleration introduced with message-security assist extension 10.

The full AES-XTS mode requires a protected key of type
PKEY_KEYTYPE_AES_XTS_128 or PKEY_KEYTYPE_AES_XTS_256.
