[media] ddbridge: board control setup, ts quirk flags
This is a backport of the board control setup from the vendor provided dddvb driver package, which does additional device initialisation based on the board_control device info values. Also backports the TS quirk flags which is used to control setup and usage of the tuner modules soldered on the bridge cards (e.g. CineCTv7, CineS2 V7, MaxA8 and the likes). Functionality originates from ddbridge vendor driver. Permission for reuse and kernel inclusion was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.
