Add support for the version 4 firmware interface and the DAC960 PG and
PJ cards. This will probably also support the AcceleRAID and eXtremeRAID cards, but nobody has volunteered one for testing, so I haven't enabled their PCI device IDs. Slightly clean up communication between the disk devices and the controller device as per new practice, and move some more register- related items int mlxreg.h from mlxvar.h. Remove some unnecessary read-modify-write operations to the card control registers; they don't behave like that. Increase the status polling interval to 10 seconds. It's still possible to load the card up to the point where a status poll will find the previous poll still running, but this will reduce the incidence of complaints.
