If a builtin dts contains the node but an external don't the fixup won't be applied. Also if the external dts does have a node + the reserved memory region nodes but the barebox builtin dts don't we do add additional reserved memory nodes which may conflict due to different name scheme: vs. @. Move the "/firmware/optee" check into the of_optee_fixup() so the check is done on the correct dtb root nodes.
