natsemi: fix MMIO for PPC 44x platforms
The driver stores the PCI resource address into 'unsigned long' variable before calling ioremap() on it. This warrants a kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion of the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.
