s390x: CPACF: Handle key wrap machine options

Check for the aes_key_wrap and dea_key_wrap machine options and set the
appropriate KVM device attribute(s) to tell the kernel to enable or disable
the AES/DEA protected key functions for the guest domain.

This patch introduces two new machine options for indicating the state of
AES/DEA key wrapping functions.  This controls whether the guest will
have access to the AES/DEA crypto functions.

aes_key_wrap="on | off" is changed to aes-key-wrap="on | off"
dea_key_wrap="on | off" is changed to dea-key-wrap="on | off"

Check for the aes-key-wrap and dea-key-wrap machine options and set the
appropriate KVM device attribute(s) to tell the kernel to enable or disable
the AES/DEA protected key functions for the guest domain.
