scsi: myrb: Add Mylex RAID controller (block interface) 

This patch adds support for the Mylex DAC960 RAID controller,
supporting the older, block-based interface only.  The driver is a
re-implementation of the original DAC960 driver.

This driver adds support for the Mylex DAC960, AcceleRAID, and
eXtremeRAID PCI RAID controllers. This driver supports the
older, block based interface.
This driver is a reimplementation of the original DAC960
driver. If you have used the DAC960 driver you should enable
this module.
To compile this driver as a module, choose M here: the
module will be called myrb.
