I think this would be easier to review if you split it up some, perhaps
cleanup such as DPRINTF(), removal of protection stuff, and qdev
conversion.

We'd probably need something like an unified DMA structure at qdev
level. Then the global DMA access and mapping routines should be
hidden inside that structure.
Another interesting case is pcnet/lance, there also the bus is
different (PCI vs. SysBus). Can we still have common DMA structure, or
do we need PCIDMA and SysBusDMA?
