From: Gowtham Suresh Kumar <gowtham.sureshkumar@arm.com>

This commit enables smm-gateway in optee-os by making the following changes:

- Updating the existing SP manifest file with a combined manifest file
  that includes information about both se-proxy and SMM gateway SP.
- Including the SMM gateway SP makefile in optee include file
  to embed smm gateway sp binary into optee image.
