register (b300). This patch prevents the creation of a new /dev/video<n>
on streaming start.

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
interrupt level.
Some subdrivers which used the image pointer have been updated.

The image pointer and its length are now in the main structure instead
of in the frame buffer. They are updated on application vidioc_qbuf and
in the URB interrupt function when ending an image.

gspca - vc032x: Webcam 041e:405b added and mi1310_soc updated.
will make the preview function not work, so I disable the 1280x1024 resolution
and revert back to the origin mi1310_soc settings.
