TEE-329-4: OP-TEE: Pass boot info to u-boot

If ATF loads OP-TEE, it will pass OP-TEE base
address and size to the u-boot through boot information.
This will help u-boot update device tree accordingly.
Note that u-boot on i.MX 8QxP does not need this information
to configure memory mapping. Query to the SC Firmware
is used instead
