Add drivers for the central and fhc busses found in enterprise class UltraSPARCs, and an eeprom attachment for fhc, which allows the date to be set properly on these machines. Central is a wierd bus which seems to only ever have 1 fhc attached to it. FHC (FireHose Controller) is another wierd bus with various things on it depending where its attached. The fhc attached to central has eeprom and zs, and the fhcs which attach directly to nexus have simm-status, environment and other nodes, none of which I'll probably ever have documentation for. Thanks to Ade Lovett for providing access to an 8 cpu e4500.

Implement interrupt resource allocation and setup. Set the interrupt group number properly based on the board id. Perform dummy reads of registers after writing to flush the hardware write buffers. This gets the soon to be committed zs attachment working.
