SMC: Initial release of smc_pa_strl, tf_daemon

These userspace components are used to load secure services in the normal
(non-secure) world. The SMC kernel driver is required to use these binaries.

Secure services enable certain security features such as
hardware-accelerated crypto, secure storage, drm, and much more.

Author: "Trusted Logic <smc_support@trusted-logic.com>." Gerrit refuses to
accept.
