This adds the Beckhoff Communication Controller (CCAT). The information
block, EEPROM interface and DMA controller are currently implemented.
The EEPROM provides production information for Beckhoff Devices.
An EEPORM binary must therefor be handed over. It should be aligned to
a power of two. If no EEPROM binary is handed over an empty EEPROM of
size 4096 is initialized.
This device is needed for the Beckhoff CX7200 board emulation.
