V4L/DVB (8833): gspca: Cleanup the sonixb code.

-the usb-id table caried several flags which were not usb-id specific but
 sensor specific, add a sensor_data array and move these flag there
-fr_h_sz was being abused to store and check which bridge was being used
 instead add a bridge member to the sd struct
-now that we have a sensor_data table use that to store pointers to
 init_sequences instead of using switch cases on sd->sensor
