V4L/DVB (11829): Rewrote frontend-attach mechanism to gain noise-less deactivation of submodules

Browse Source 
This patch is reorganizing the frontend-attach mechanism in order to
gain noise-less (superflous prints) deactivation of submodules.

Credits go to Uwe Bugla for helping to clean and test the code.
