[yocto] [PATCH] runtime: add BSP test case for usb storage

[Mike Looijmans]

I would not write to flash media in this test. It's pointless, if you can read 
the the device, it means that you can already send commands and data to it, 
and reading will thus test data going in both directions already. Writing to 
the media will just wear it out, and if there's a problem unmounting it, it 
may lead to a corrupted filesystem and yield unpredictable future results.
