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.
