Add AMI Megaraid card to new driver (resend)

This is the fourth submission of this patch. I have still had no response from the maintainer.

Adds AMI Megaraid Elite 1600 to the list of supported adapters. I encountered some issues running with the old megaraid driver with this card, so I wrote this patch and have been running without problems since mid December. Please apply.

Here is the PCI config space dump of my controller:
