Add device nodes for all I2C EEPROMs on the Falcon board stack.
Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

Probably we want to move the sub board nodes to separate .dtsi files.
The EEPROM on the CPU board contains some data.
All other EEPROMs are present, but in pristine state (all ones).
