refactor(tc): move DTB to start of DRAM
Now that tf-a passes the DTB address to BL33, its location doesn't
matter. Since we declare a fixed size for it (32K) put it at the start
of ram to not fragment memory. This has the added benefit of
"supporting" larger kernel sizes which are breaking with the current
location.

refactor(tc): correlate secure world addresses with platform_def
Similarly to the memory node in the NS device tree, platform_def already
defines all the necessary values to populate the spmc manifest and NS
related entries automatically. Use the macros directly so any changes
can propagate automatically.
The result of this is that TC3 and above get correct secure world
manifests automatically. They were previously broken.
One "breaking" change is that the FWU region moves. This should have
happened previously but it was missed when the secure portion of DRAM
was increased, leaving it in secure memory. This was caught when going
over the definitions and correlating them should prevent this in the
future.

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.
