Import new version of the HPTMV driver from Highpoint. The major change
here is the support for amd64, as well as possible support for PAE. Many
thanks to Highpoint for continuing to support FreeBSD.

Move all of the hptmv files to /sys/dev/hptmv so that they won't be mistaken
for being on a CVS vendor branch. The files were moved via a repo-copy.

Import the HighPoint RocketRAID 182x driver. Thanks to HighPoint for
providing the original driver, and thanks to IronSystems for providing
hardware for testing.
