Insert and modify ov3640.c, Kconfig and Makefile under kernel/drivers/media/video/ of omap's linux

I want to use ov3640 camera module in devkit8000 operated by android (0xdroid of 0xlab) powered by linux 2.6.29-omap1, but there is not ov3640 device driver. In googling, I found that in rowboat's kernel; it is google's another distribution based on beagleboard of omap3. Therefore, it need some changes.

1. copy ov3640.c and ov3640.h to drivers/media/video

2. Edit Kconfig under drivers/media/video
