V4L/DVB (6134): tuner: alter build to produce separate modules

Break tuner.ko into separate modules. This was a quick change -
Tuner sub-drivers are still static-linked to tuner.ko, this will
change after using dvb_attach and removing the probing functions.

After this change, one can deselect undesired tuner sub-drivers via Kconfig.
