V4L/DVB (7836): cinergyT2 build fix

x86.git testing found the following build bug in v2.6.26-rc1:

  drivers/built-in.o: In function `cinergyt2_probe':
  cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
  cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'
  cinergyT2.c:(.text+0xb623d): undefined reference to `input_free_device'

with the following config:

  http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad

The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still possible
to build CONFIG_DVB_CINERGYT2=y - which leads to missing symbols.

The solution is to make DVB_CINERGYT2 dependent on INPUT.

[ This solves the build problem - i have not tested the driver on this card. ]
