media: imx: set a media_device bus_info string
[ Upstream commit 6d0d779b212c27293d9ccb4da092ff0ccb6efa39 ]
Some tools like v4l2-compliance let users select a media device based
on the bus_info string which can be quite convenient. Use a unique
string for that.
This also fixes the following v4l2-compliance warning:
warn: v4l2-test-media.cpp(52): empty bus_info
