I'd lower this to dev_dbg() and print the jedec id. It might come in
handy for a quick glance during bootup if debug is enabled.

Part of this is already available through the spi-nor debugfs, although 
not
the actual mtd properties. These I think, should go into the mtdcore
itself if really needed. Either through dev_dbg() or debugfs.
