[media] vino/saa7191: remove deprecated drivers 

These drivers haven't been tested in a long, long time. The hardware is
ancient and hopelessly obsolete. These drivers also need to be converted
to newer media frameworks but due to the lack of hardware that's going
to be impossible.

So these drivers are a prime candidate for removal. If someone is
interested in working on these drivers to prevent their removal, then
please contact the linux-media mailinglist.

These drivers are already deprecated, so now remove them altogether.

Say Y here to build in support for the Vino video input system found
on SGI Indy machines.
This driver is deprecated and will be removed soon. If you have
hardware for this and you want to work on this driver, then contact
the linux-media mailinglist.

Support for the Philips SAA7191 video decoder.
This driver is deprecated and will be removed soon. If you have
hardware for this and you want to work on this driver, then contact
the linux-media mailinglist.
To compile this driver as a module, choose M here: the
module will be called saa7191.
