PCI: Use pci_generic_prep_mwi on sparc64
The setting of the CACHE_LINE_SIZE register in sparc64's pci initialisation code isn't quite adequate as the device may have incompatible requirements. The generic code tests for this, so switch sparc64 over to using it. Since sparc64 has different L1 cache line size and PCI cache line size, it would need to override the generic code like i386 and ia64 do. We know what the cache line size is at compile time though, so introduce a new optional constant PCI_CACHE_LINE_BYTES.
