Enable SWUpdate support for bbb, update Isar

This primarily enables A/B rootfs SWUpdate for the BeagleBone Black, but also updates the Isar revision and fixes an accidental host-side dependency of the SWUpdate build.

Does anyone know how to make secure boot work with the BBB? Enabling the software path should be just about building the needed config, but then we still lack first-stage firmware validation by the hardware.

Next, it would be good to enable also a physical arm64 reference board for SWUpdate. Any suggestions?
