libsp: Add build system files.
- Add opteesp deployment.
This deployment builds libsp as a static library targeting aarch64
SPs running under OP-TEE.
- Add inport and export interfaces for OP TEE-OS.
- Add opteesp environment files.
- Add shared CMake scripts including GCC compiler support.

+ Abstraction to interface to SP DEV KIT.
+ ---------------------------------------
+
+ SP DEV KIT is a component generated by the OP-TEE OS build and defines the
+ FF-A SP interface for the OS to SPs.
+
+ This file provides the following functionality:
+ - creates a static library to easy building the SP side component of the
+ SP DEV KIT. This library will be properly configured with transitive
+ dependencies to apply the needed compiler configurations to the
+ target linking against it.
+ - defines a function to allow configuration of the linking phase of the
+ executable target. (See: :command:`sp_dev_kit_configure_linking`)
+
+ Inputs:
+ ``SP_DEV_KIT_DIR``
+ A cmake or environment variable specifying the location of the SP DEV KIT.
+ This is mandatory.
+
+ ``SP_DEV_KIT_INC_DIR``
+ The SP DEV KIT depends on some header files living in the SP. This variable
+ must be set to an include path giving access to these headers.
+
+ Outputs:
+ :command:sp_dev_kit_configure_linking()
+
+ :variable:`SP_DEV_KIT_LIBRARIES`
