boot/uboot: add support for bundling TEE in ELF format into U-Boot

Browse Source 
Some U-Boot platforms (e.g. rockchip) can bundle OPTEE's tee.elf
into the U-Boot image. This patch brings the necessary changes to
enable this feature.

Some platforms (such as Rockchip) encapsulate the TEE inside
U-Boot. This option makes sure optee-os gets built prior to
U-Boot, and that the TEE variable pointing to OPTEE's
tee.elf, is passed during the Buildroot build.
