Update .Dt to reflect the fact that these drivers and man pages are
installed on more than just i386.

Move man pages out of man4.i386. Most of them are applicable to amd64
too, so, instead of descending to the i386 directory, we add some magic to
the parent Makefile.
These man pages refer to drivers that I'm aware that work on amd64. Most
likely there are more, but I'll deal with them later.
