The DT bindings of upstream linux kernel have diverged and are not
backward compatible so we embed a DTB in FW_PAYLOAD which follows
upstream linux kernel DT bindings. The U-Boot drivers will also be
fixed to use the updated DT bindings as-per upstream Linux kernel.

By embedding updated DTS in FW_PAYLOAD, we allow users to easily
migrate to update DT bindings using OpenSBI+U-Boot.
