[media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl
Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver.
