The returned value of i2c read is a 16 bits word. It was stored in
a 8 bits variable, preventing a sensor to be detected.

  the sensor
-remove USB-id's from sn9c102 for cams where sn9c102 does not support the
  bridge sensor combination
-no longer make inclusion of usb id's removed from zc0301 and sn9c102
  conditional in gspca
-fix conditional inclusion of USB-id's in gspca to also work when the
  conflicting drivers are build as a module
-add a number of USB-id's to gspca from various windows .inf files:
0c45:608f from generic sonix sn9c103 inf file (+ ov7630 which we support)
041e:4022 from creative webcam nx pro, same as already supported 041e:401e

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags,
and sets this flag for the Philips SPC200NC cam (which has its sensor installed
upside down). The same flag is also needed and added for the Philips SPC300NC.

Together with a patch to libv4l which adds flipping the image in software this
fixes the upside down display with the SPC200NC cam.
