Harald Freudenberger 4da57a2fea s390/zcrypt: extend cca_findcard function and helper
Rework and extension of the cca_findcard function to be prepared for
other types of secure key blobs. Split the function and extract an
internal function which has no awareness of key blobs any
more. Improve this function and the helper code around to be able to
check for a minimal crypto card hardware level (Background: the newer
AES cipher keys need to match to the master key verification pattern
and need to have a crypto card CEX6 or higher).

No API change, neither for the in-kernel API nor the ioctl interface.
