net-misc/dahdi: build fixes.

There were still some cases where specific kernel versions wouldn't
compile.  This now compiles on all versions that I've got.

Consolidated the patches for non-digium hardware (which is where most of
the issues were).

Added a patch for dealing with 64-bit division on PPC (works on amd64),
untested on ppc where it's required.  Will also affect ARM now - as per
newest keyword request.

Fix for systems without CONFIG_PCI.

Nuke empty RDEPEND= and DEPEND= lines.
