[PATCH] Add ATP88x support to the ATP870U driver (Vendor patch) 

Patch-by: ARTOP Corp.

Basically this adds the small bits for the new card and makes one set of items
an array because the new card is multi-channel.

This driver supports the ACARD 870U/W SCSI host adapter.
This driver supports the ACARD SCSI host adapter.
Support Chip <ATP870 ATP876 ATP880 ATP885>
To compile this driver as a module, choose M here: the
module will be called atp870u.
