mn10300: drop dead code
pci-iomap.c was (apparently, mistakenly) reintroduced as part of commit 83c2dc15ce824450e7044b9f90cd529c25747ae0 MN10300: Handle cacheable PCI regions in pci_iomap() probably as side-effect of forward-porting the patch from an old kernel. It's not really needed: the generic pci_iomap does the right thing here. The new file isn't compiled so it's safe to drop.
