utils: Add the omnia-mcutool utility
Add a new utility, omnia-mcutool, which main purpose is to upgrade the
firmware on the microcontroller on the Turris Omnia router. Depends on
omnia-mcu-firmware, and the upgrade process is pretty simple:
omnia-mcutool --upgrade
Besides firmware upgrade, the utility can be used to show and configure
various firmware settings.
