s390/ipl: fix virtual vs physical address confusion
The value of ipl_cert_list_addr boot variable contains
a physical address, which is used directly. That works
because virtual and physical address spaces are currently
the same, but otherwise it is wrong.
While at it, fix also a comment for the platform keyring.
