target-mips: DMA support for RC4030 chipset
Attached patch implements DMA support to RC4030 chipset and simplifies
jazz IO part (at 0xf0000000), where registers contain 16 bit values.
Config register has not a clear meaning (only one value is always valid,
and sometimes another one), so use a magic value instead.
The patch also wires DMA transfers for the SCSI adapter in the Jazz
emulation (Mips Magnum 4000 and Acer Pica 61).
