'fdt systemsetup' wasn't working, due to the fact that the 'set' command
was being parsed in do_fdt() by only testing for the leading 's' instead
of "se", which kept the "sys" test further down from executing. Changed
to test for "se" instead, now 'fdt systemsetup' works (to test the
ft_system_setup proc w/o having to boot a kernel).

This adds to the DT the I2C controllers that connect to the board ID EEPROM,
camera board EEPROM, etc. With this change, you can now probe all I2C devices
on a TX1 board.
