tuner-core cleanups

The entire subsystem internals have changed, but without enough care to clean up tuner-core internals.

This patch series take care of tuner-core, removing some dead code there, and avoiding the risk of returning T_STANDBY to userspace.

Those changes were motivated by this thread:

The patches are tested with both radio and xawtv applications with a Pixelview Ultra device (cx88 card=27). This device has a separate FM tuner, with makes tuner-core life harder, as tuner-core needs to filter if a tune event should go to tea5767 FM tuner, or to an analogic tuner (Tena/TNF, in the case of the board I used for tests).
