hppa: Add support for LASI chip with i82596 NIC

Browse source 
LASI is a built-in multi-I/O chip which supports serial, parallel,
network (Intel i82596 Apricot), sound and other functionalities.
LASI has been used in many HP PARISC machines.
This patch adds the necessary parts to allow Linux and HP-UX to detect
LASI and the network card.
