[media] v4l2: drop V4L2_CHIP_MATCH_SUBDEV_NAME
After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.
