sh: pci: Disable MWI and make pci_dma_burst_advice() a bit more accurate.
None of the SH PCI controllers support MWI, it is always treated as a direct memory write, so simply disable it outright. In the case of the PCI cache line size, consult that for the pci_dma_burst_advice() strategy, and switch over to PCI_DMA_BURST_MULTIPLE, as PPC64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
