plat/tc: add firmware update secure partition support
- add the target for the Firmware Update secure partition. The secure partition is larger than the other partitions because the FIP is a large file (~4MB) and needs to be stored entirely in a secure world buffer before it's written into the NV storage.
- memory map the NOR Flash address space
- increment MAX_XLAT_TABLES to accomodate the mapping of the NOR flash device.
