FWU: Add documentation for Firmware Update feature
This patch adds design documentation for the Firmware Update (FWU)
feature in `firmware-update.md`. It provides an overview of FWU,
describes the BL1 SMC interface, and includes diagrams showing
an example FWU boot flow and the FWU state machine.
This patch also updates the existing TF documents where needed:
* `porting-guide.md`
* `user-guide.md`
* `firmware-design.md`
* `rt-svc-writers-guide.md`
* `trusted_board_boot.md`
