[PATCH] media: imx: set a media_device bus_info string

[Martin Kepplinger]

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
