It seems the 'Notebook' vendor is padded with spaces in the DMI data, and so
the GUID changes now we're following the same stripping scheme of Windows 10.
The setup() is the counterpart to probe(), the difference being the former needs
the device open and the latter does not.
This allows objects that derive from FuDevice, and use FuDeviceLocker to use
open() and close() without worrying about the performance implications of
probing the hardware, i.e. open() now simply opens a file or device.
