Add trm - driver for Tekram TRM-S1040 cards (DC395U/UW/F,DC315/U).

Thanks to Tekram for donating a couple of cards and a NetBSD driver by
Erich Chen of Tekram. Thanks to Martin Akesson for a first port of the
NetBSD driver to OpenBSD and thanks to Ashley Martens for the major
cleanup to make it presentable and style(9)ish.

Only tested on i386 at this time.
