Subject: Patch to ftdi_eeprom for generating checksum

I recently had an issue with a bad eeprom in an FT232H module and needed to hand craft an eeprom image from a mix of a generated image and the one which shipped with the board. I don't have a windows system to use the FTDI utility.

I modified ftdi_eeprom to be able to generate the checksum when using the flash_raw option - attached is the patch (against head) if you are interested.
