s390/io: Add pci_iomap_wc() and pci_iomap_wc_range()

The following commit:

  1b3d4200 ("PCI: Add pci_iomap_wc() variants")

Introduced pci_iomap_wc() variants but broke the s390 build,
because s390 requires its own implementation of pcio_iomap*()
calls.

The reason for that is that:

  "BAR spaces are not disjunctive on s390 so we need the bar
   parameter of pci_iomap to find the corresponding device
   and create the mapping cookie"

so it has its own lookup/lock solution and it does not include
asm-generic/pci_iomap.h.

Since it currenty maps ioremap_wc() to ioremap_nocache() and
that's the architecture default we can easily just map the wc
calls to the default calls as well.
