Raghu Krishnamurthy 6a88ec8b30 feat(rmmd): el3 token sign during attestation ... Add required SMCs by RMM to push attestation signing requests to EL3 and get responses. EL3 may then choose to push these requests to a HES as suitable for a platform. This patch also supports the new RMM_EL3_FEATURES interface, that RMM can use to query for support for HES based signing. The new interface exposes a feature register with different bits defining different discoverable features. This new interface is available starting the 0.4 version of the RMM-EL3 interface, causing the version to bump up. This patch also adds a platform port for FVP that implements the platform hooks required to enable the new SMCs, but it does not push to a HES and instead copies a zeroed buffer in EL3.
