s390/io: Add pci_iomap_wc() and pci_iomap_wc_range()
The following commit: 1b3d4200c1e0 ("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.
