[media] tlg2300: remove deprecated staging driver 

This driver hasn't been tested in a long, long time. The company that made
this chip has gone bust many years ago and hardware using this chip is next
to impossible to find.

This driver needs to be converted to newer media frameworks but due to the
lack of hardware that's going to be impossible. Since cheap alternatives are
easily available, there is little point in keeping this driver alive.

This driver is already deprecated, so now remove it altogether.

This is a video4linux driver for Telegent tlg2300 based TV cards.
The driver supports V4L2, DVB-T and radio.
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 poseidon
