pvrusb2: Improve handling of routing schemes

From: Mike Isely <isely@pobox.com>

The pvrusb2 driver has a concept of "routing scheme" which defines
which physical inputs should be connected based on application's
choice of logical input.  The correct "routing scheme" depends on the
specific device since different devices might wire up their muxes
differently - it can't be coded into the sub-device driver and it
can't be just a single setting in the pvrusb2 driver since the driver
handles multiple different devices.  This concept has been in place
for a while and works, however there are cases where a specific input
for a specific device has no route - previously due to an oversight
this was handled badly.  With these changes the driver can now
specifically recognize cases where there is no defined route for a
given input.
