chain-loading to Linux via a TEE.

With this patch in-place you can generate a bootable OPTEE image like this:

mkimage -A arm -T kernel -O tee -C none -d tee.bin uTee.optee

where "tee.bin" is the input binary prefixed with an OPTEE header and
uTee.optee is the output prefixed with a u-boot wrapper header.

This image type "-T kernel -O tee" is differentiated from the existing
IH_TYPE_TEE "-T tee" in that the IH_TYPE is installed by u-boot (flow
control returns to u-boot) whereas for the new IH_OS_TEE control passes to
the OPTEE firmware and the firmware chainloads onto Linux.
