sound/pci updates

[Eduardo Tongson]

* Audio drivers failed to detect failure condition and attempted to
assign DMA address to the wrong address. It can cause system lockup
or other mysterious errors. Since most sound cards requires low DMA
address(BUS_SPACE_MAXADDR_24BIT) sndbuf_alloc() would fail when the
audio driver is loaded after long running of operations.
* Added support for the Vibra 128 (and other CT4730-based cards) on es137x.
