Enable pcie snoop for SB600 and MCP51. Fixes a variety of noise,

looping and distortion problems.  This is a temporary solution until
we get something like the BUS_DMA_NOCACHE flag to bus_dmamem_map(9),
which came with the driver when ported from NetBSD but means nothing
here.  It's likely that other NVIDIA and ATI chipsets will need this,
but I'd rather have some testers before adding them in.
