The default_value for the Bt878 V4L2_CID_CONTRAST control is currently set to 32768. Internally this gets translated to an analog input circuit gain of 1.19. However, the default gain should be 1.0. This patch alters the default value to 27648 which corresponds to a gain of 1.0. It also alters the probe routine so that the correct value is written on board initialisation.
