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.

The lasi_82596_init() function should not belong to the device in
hw/net/lasi_i82596.c since it attempts to wire up the NIC in a sysbus-specific way
which is not valid for other buses.
Having a look at lasi_82596_init() there are a few things wrong with it:
- qemu_create_nic_device() should be done in lasi_82596_instance_init()
- s->state.irq should not be set directly, but instead be initialised
as a qdev gpio in lasi_82596_instance_init() and then connected by the board
One solution might be to make these changes and then move the remainder of
lasi_82596_init() into hw/hppa/machine.c and then remove the function declaration
from the lasi_82596.h.

This should be TYPE_LASI_82596.
