The LK bootloader on Pixel6 searches for a dt overlay in the
dtbo partition with a board_id and board_rev that matches
what is baked into the device. 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.
