feat(tc): add firmware update secure partition
Firmware update is a trusted service secure partition that implements
the PSA firmware update specification. It executes in the secure world
in total compute platform. To make it fit with Op-tee we need to reduce
its available memory.
Also, reserve 4 MB for stmm communication used for firmware update.
The firmware update secure partition and u-boot communicates using the
stmm communication layer and it needs a dedicated memory region.
