Values for registers to be set at camera init.

For this camera, these values aren't really mentioned in the datasheet and instead contact has to be made with OmniVision to get the best values. Instead of doing that myself, these values are from the Linux kernel driver for this camera, these values came from OmniVision.

The camera init should be done in this order too. These settings give VGA VUYU, 30fps COM7 software reset value.

Writing 0x80 to the COM7 register sets all registers to their default value. Default does not mean optimal though.

This is recommended to be run at the very start of the driver init.
