V4L/DVB (5610): M920x: remove duplicated code
Some of the devices supported by the m920x driver have identical functions used for tuner_attach and frontend_attach. This patch consolidates the functions in question, and updates the debug code to be generic for each. This patch decreases the size of the kernel.
