The "CAN stuff" is just a binary power read-out, routed from an external CAN
card, which may or may not be present. The CAN card is not accessed from
within this driver. This situation arises because our h/w developer team
decided to integrate various unrelated pieces of functionality into the
same hardware card (even into the same 8-bit register).

This arcx-anybus controller card has two unrelated pieces of functionality:
1. implements an anybus-s slot
2. implements a power read-out from an external CAN card

This situation is not ideal but it's what we have :)
