net/dp8393x improvements

Hi,

This patchset improves dp8393x network card emulation to current QEMU standards, mostly decouples it from MIPS rc4030 chipset emulation, and add PROM and load/save functionalities.
Only required cleanup has been done on the rc4030 side.

Patchset has been tested on MIPS Jazz emulation and on (yet unpublished) m68k Quadra 800 emulation.

I expect those patches go through a MIPS tree, as rc4030 and dp8393x are currently only used in MIPS Jazz emulation.

Hervé Poussineau (8):
rc4030: create custom DMA address space
rc4030: use AddressSpace and address_space_rw in users net/dp8393x: always calculate proper checksums net/dp8393x: do not use old_mmio accesses net/dp8393x: use dp8393x_ prefix for all functions net/dp8393x: QOM'ify
net/dp8393x: add PROM to store MAC address net/dp8393x: add load/save support
