            sbus.c sbusvar.h

Log Message:
Overhaul streaming buffer handling:

        sysio streaming buffer flushes write a single 8-byte aligned 8-byte
        value.

        psycho streaming buffer flushes write a 64-byte aligned 64-byte block.

So separate out the streaming buffers into their own structure and pass those
in to all iommu operations.  This also means we only flush the correct
streaming buffer for psycho rather than needing to flush both just in case.
