Alexander Gordeev d1ad2eb081 s390/ipl: fix IPIB virtual vs physical address confusion 
[ Upstream commit 2facd5d398 ]

The pointer to IPL Parameter Information Block is stored
in the absolute lowcore for later use by dump tools. That
pointer is a virtual address, though it should be physical
instead.

Note, this does not fix a real issue, since virtual and
physical addresses are currently the same.
