Stefan Haberland e67f630086 zipl: check for valid ipl parmblock lowcore pointer ...

The lowcore parmblock pointer is not valid in every case. For example
it is invalid for CCW type IPL.
To have an indication if the pointer is valid do a diag308 to store the
parmblock and check if secure boot is enabled.
If it is enabled the lowcore pointer is valid and the ipl report that is
needed for secure boot can be found right behind the ipl parmblock.
