iomap: fix 64 bits resources on 32 bits
Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency.
