- Adjust hstart in ov7630 on sn9c103 initdata to shift bayer pattern, this is
 the same change as done for the other initdata tables in a previous patch.
- Assign usb-id's for the ov7630 + sn9c103 to gspca if gspca and sn9c102
  drivers are both enabled.

-Make raw bayer header size change from 20 to 16 affect rev072a only, my 2
 rev012a cams both have a header size of 20
-While testing this I also tested the new exposure setting (good work on
 finding the register JF), and after quite a bit of testing have found out the
 exact meaning of the register, this patch modifies setexposure to control
 the exposure over a much wider range.

When using the sonixb driver in a dark room and given that the autoexposure
algorithm starts with a setting most suitable for daylight, the picture
produced by the cam may actually be 100% black leading to a avg_lum value of 0,
so an avg_lum value of 0 does not always signal an exposure settings change
(which it normally does). This patch adds a check for the really black image
case and stops dropping all frames as invalid in this case.

This patch makes gspca claim the USB-ID for sn9c101/2 cams with a TAS5110C1B
sensor even if both gspca and sn9c102 are enabled, as these cams are much
better supported under gspca (and extensively tested with gspca).
It also removes an usb-id from sn9c102 for one more unsupported bridge
sensor combo.

- Add support for vga modes (320x240, 160x120) for sif sensors
- Remove F_RAW sensor flag raw mode should work on any sensor as its a bridge

1) Lower the hstart setting for all sensor by 1 so that we generate
   (compressed) BGGR data just like sn9c102 does (instead of GBRG data)
2) Add support for raw bayer output in the lowest resolutions (not enough
   bandwidth for higher resolutions), this should work with all sensors but
   to be sure only enable it for sensors where it has been tested.

-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

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.
