Enable the i82596 network chip which is included in the LASI
multi I/O chip. Since LASI has different start addresses on
the various machines, always initialize the LASI components
by their offsets.
As suggested by Mark Cave-Ayland <[email protected]>
Changes since v1:
Added proper Qemu device initialization for LASI

One thing I noticed: Those defines are now duplicated.
Example:
hw/hppa/hppa_hardware.h:#define LASI_LAN 0x07000
include/hw/misc/lasi.h:#define LASI_LAN 0x07000
Yes. The file hppa_hardware is shared with SeaBIOS, that's why it's
currently duplicately defined. Will try to clean up with later patches,
but for now it's the best way.
