TPCI-200
--------
* It receives the name of the mezzanine plugged in each slot by SYSFS.
No autodetection supported yet, because the mezzanine driver could not be
loaded at the time that the tpci200 driver loads.
* It has a linked list with the tpci200 devices it is managing. Get rid of it
and use driver_for_each_device() instead.
