media: ov6650: Fix MODULE_DESCRIPTION

Commit 23a52386 ("media: ov6650: convert to standalone v4l2
subdevice") converted the driver from a soc_camera sensor to a
standalone V4L subdevice driver.  Unfortunately, module description was
not updated to reflect the change.  Fix it.

While being at it, update email address of the module author.
