Improve chip matching in v4l2_register for VIDIOC_DBG_G/S_REGISTER
From: Hans Verkuil <hverkuil@xs4all.nl>
The chip matching in struct v4l2_register was rather primitive. It could
not be extended to other busses besides i2c and it lacked a way to
differentiate between two i2c chips driven by the same driver on one
board (e.g. a PVR500 with two tuner chips, one for analog TV and one for
radio).
It has now been improved making it much more powerful.
