s390x/ipl: Extend the IplParameterBlock struct
The IplParameterBlock struct currently has only 200 bytes filled, but it
can be up to 4K.
This patch converts the struct to union with a fully populated struct
inside it and second struct with old values.
For compatibility reasons we disable migration of the extended iplb
field for pre-2.7 machines. Also a guest still can read/write only the
first 200 bytes of IPLB for now.
