upstream: [media] smiapp: Use I2C adapter ID and address in the sub-device name

The sub-device names should be unique. Should two identical sensors be
present in the same media device they would be indistinguishable. The names
will change e.g. from "vs6555 pixel array" to "vs6555 1-0010 pixel array".
