utils: Add the omnia-eeprom utility

Browse Source 
Add a new utility, `omnia-eeprom`, which can be used to print / set
EEPROM fields on Turris Omnia.

One example when this utility might be useful is if the board
experiences random crashes due to newer versions of the DDR training
algorithm in newer U-Boot. The user can change the DDR speed from 1600K
to 1333H to solve these issues, with

  ```
  omnia-eeprom set ddr_speed 1333H
  ```
