hornet.cpp, nwk-tr.cpp: extracted nwk-tr.cpp lan board implementation to a device and hooked it up to thrilldbu in hornet.cpp. It doesn't reset anymore but needs analog controls hook-up

This pcb is the same as the A version but with one added chip:
2G - XICOR X76F041 Secure SerialFlash (SOIC8)
Note: This chip is also present on *some* Hornet games on the GN715 CPU board at location
30C. The chip refreshes game and region specific serial data to the Timekeeper RAM if the
region ID matches the timekeeper. Because Racing Jam 2 and Thrill Drive came in a conversion
kit for Racing Jam, the two former games will first boot with a "backup data error" because
because of the timekeeper used for the incorrect game. Pressing the test switch then sets the
timekeeper back to factory settings for the new kitted game installed. If the region ID in
serialflash and timekeeper do not match, the game boots with a "hardware error" message.
TODO:
- Add X76F041 device when dumps will be available and get rid of the work_ram hack
