s390/setup: Fix __pa/__va for modules under non-GPL licenses

[ Upstream commit e188e5d5ffd01d484b5255b88739fcf67b300223 ]

The struct vm_layout contains fields used in __pa/__va calculations. Such
fundamental things have to be exported with EXPORT_SYMBOL to avoid
breakages of out-of-tree modules under non-GPL licenses.
