s390/entry: sort out physical vs virtual pointers usage in sie64a
Fix virtual vs physical address confusion (which currently are the
same).
sie_block is accessed in entry.S and passed it to hardware, which is why
both its physical and virtual address are needed. To avoid every caller
having to do the virtual-physical conversion, add a new function sie64a()
which converts the virtual address to physical.
