s390/ipl: make parameter area accessible via struct parmarea
Since commit 9a965ea95135 ("s390/kexec_file: Simplify parmarea
access") we have struct parmarea which describes the layout of the
kernel parameter area.
Make the kernel parameter area available as global variable parmarea
of type struct parmarea, which allows to easily access its members.
