If this overlay is not present then the phone will bootloop in fastboot and you can't boot the upstream kernel. This commit adds a dtbo for the production oriole variant. The other pre-production board overlays are not included at this time. Adding the dtbo here allows for a better experience when building/booting the upstream kernel on Pixel devices as all the DT required to boot the device will be created as part of the kernel build process. Rather than having to fetch the dtbo from some other repo.
