Move tuners to common/tuners

There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.

This patch moves those common tuners into a common dir. It also moves saa7146
driver into drivers/media/video, where other hybrid drivers are placed.

Kconfig items were rearranged, to split V4L/DVB core from their drivers.
