feat(optee): add device tree for coreboot table

This adds creation of a device tree that will be passed to OP-TEE.
Currently that device tree only contains the coreboot table per the
Linux coreboot device tree specification. This device tree is then
passed to OP-TEE so it can extract the CBMEM console information from
the coreboot table for logging purposes.
