Modified Files:
        src/sys/arch/powerpc/powerpc: bus_dma.c

Log Message:
Don't forget to advance within the segment in _bus_dmamap_load_raw.

This went unnoticed, because the function is rarely used. While it is
wired in PowerPC DMA routines, no PowerPC specific drivers actually
use it. It only appears in a few MI drivers.

With small _dm_segcnt, load just failed with EFBIG, with large value
all segments pointed to the same page, which resulted in corrupting
the transfer.
