v2.0.0

This is a major update of nerves_system_rpi3 that changes the MicroSD/eMMC
layout in order to support automatic rollback of non-working firmware updates.

IMPORTANT This is a one way upgrade. Going back to the old partitioning
requires manually reflashing of the RPi's storage.

Previous releases assumed that firmware updates worked. This one requires that
firmware images mark themselves as good using
Nerves.Runtime.validate_firmware/0. See Nerves.Runtime for more information
on this. Firmware not marked as good reverts back to the previous version.
