zorro: ZTWO_VADDR() should return "void __iomem *"
ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should return "void __iomem *" instead of "unsigned long". This allows to drop several casts, but requires adding a few casts to accomodate legacy driver frameworks that store "unsigned long" I/O addresses.
