This allows secure partitions to access these registers. This is needed in some cases. For example, it has been reported that in order to implement secure storage services, a secure partition needs to encrypt/decrypt some authentication variables, which requires FP/SIMD support. Note that SPM will not do any saving/restoring of these registers on behalf of the SP. This falls under the SP's responsibility. Also note that if the SP gets preempted, it might not get a chance to save/restore FP/SIMD registers first. This patch does not address this problem. It only serves as a temporary solution to unblock development on the secure partition side.
