media: tm6000: deprecate this driver

Deprecate the tm6000 driver. This driver does not use the vb2 framework
for video streaming, instead it uses the old videobuf framework.

We want to get rid of these old drivers, so deprecated it for future
removal.

+This is one of the few drivers still not using the vb2
+framework, so this driver is now deprecated with the intent of

+In order to keep this driver it has to be converted to vb2.
