rather than setting a fixed value at module insertion.

The indirect registers at 0x1c/0x1d control frame settings. If we
leave the values at 0x0a and 0x0b at their reset-time defaults, frame
data from the camera matches the UVC payload format. This lets us
better reassemble the data into frames and know when data was lost.
This also lets us relax the bulk_size requirement from 600K to 2K,
which should help systems on with limited RAM (like the PS3).

The frame size is too small, so we lose the last YUYV pixel.
Fix the setup and remove the last_pixel hack.

The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE,
it is found also in other webcams like Hercules Blog Webcam and
Hercules Dualpix HD.
This driver is the port to gspca of a prototype driver by Mark Ferrell
based on vivi. The original code to initialize the camera and start the
capture is from Jim Paris on ps2dev.org, here integrated with the analysis
of the USB communications taken by the windows driver.
