VIRT_TO_BUS is only used for legacy device PCI and ISA drivers using virt_to_bus() instead of the streaming DMA mapping API, and the remaining drivers generally don't work on 64-bit architectures. Two of these drivers also cause a build warning on s390, so instead of trying to fix that, let's just disable the option as we do on most architectures now.
