Modified Files:
        src/sys/arch/arc/jazz: asc.c

Log Message:
- <machine/param.h> says:
  "XXX Maxphys temporary changed to 32K while SCSI driver is fixed."
  I (and soda) don't know what the "SCSI driver" is, but add local
  asc_minphys() to limit max xfer size only for asc.c for now.
- According to old asc.c driver, DMA_START() is called before NCR_CMD_DMA
  command. I'm not sure which DMAC or ASC should be started first, but
  move DMA command from asc_dma_go() to asc_dma_setup().
- Disable NCR_F_DMASELECT (which allows DMA xfer for select command)
  since it caused some problem on PICA.

Now gxemul-0.3.6.2 reaches mountroot() sd0 (but can't exec /sbin/init yet).
