FMC: add a driver to write mezzanine EEPROM

This driver allows to reprogram the EEPROM in a mezzanine, to store
its own identifiers during manufacturing or to save other useful data.

+        help
+          This driver matches every mezzanine device and can write the
+          internal EEPROM of the PCB, using the firmware loader to get
+          its binary and the function carrier->reprogram to actually do it.
+          It is useful when the mezzanines are produced.
