Embarrassingly we never told the non-secure world that secure firmware
lives in the first few hundred KBs of DRAM, so any non-secure payload
could happily overwrite TF-A, and we couldn't even blame it.
Advertise the BL31 region in the reserved-memory DT node, so non-secure
world stays out of it.
This fixes Linux booting on FPGAs with less memory than usual.
