        src/sys/arch/amiga/amiga: device.h
        src/sys/arch/amiga/dev: ahsc.c atzsc.c cbiiisc.c grf_cv.c grf_cvreg.h
            gtsc.c sbic.c sbicreg.h siop2.c

Log Message:
Added two new macros to device.h:
amiga_membarrier() enforces a reorder protection on memory read/writes.
amiga_cpu_sync() makes sure the instruction pipelines are flushed.
Both macros may be used in all amiga device drivers for compatibility with
amigappc. For the start I fixed some SCSI drivers.
cbiiisc and ahsc were tested and seem to work really fast with DMA now.
Some stability problems with amigappc remain nevertheless (spontaneous
kernel DSI traps with high CPU/SCSI load).
