From: Jan Kiszka <jan.kiszka@siemens.com>

Analogously to TF-A, this adds an include file to be used in custom
Open Portable Trusted Execution Environment. The typical customization
points are OPTEE_PLATFORM and possibly a couple of
OPTEE_EXTRA_BUILDARGS. The to-be-packaged binaries can be defined via
OPTEE_BINARIES.

Changes in v3:
 - account for platform flavors in OPTEE_PLATFORM
