Bjorn Helgaas 45ea2a5fed PCI: Don't use 64-bit bus addresses on PA-RISC
Meelis and Helge reported that 3a9ad0b4fd ("PCI: Add pci_bus_addr_t")
caused HPMCs on A500 and hangs on rp5470.

PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so
prior to 3a9ad0b4fd, we always used 32-bit PCI addresses.  After
3a9ad0b4fd, we do use 64-bit PCI addresses in 64-bit kernels, and
apparently there's some PA-RISC problem related to them.

Fixes: 3a9ad0b4fd ("PCI: Add pci_bus_addr_t")
