V4L/DVB (12770): Add tm6000 driver to staging tree

Adds a driver for Trident TV Master tm5600/tm6000 chips.

Those USB devices are usually found with a Xceive xc2028/xc3028
tuner, although the firmware seems to be modified to work with
those chips on some older devices.

+
+	  Since these cards have no MPEG decoder onboard, they transmit
+	  only compressed MPEG data over the usb bus, so you need
+	  an external software decoder to watch TV on your computer.
+
+	  Say Y if you own such a device and want to use it.
