TSPD: Explicitly allow NS preemption for Yielding SMCs
When EL3 exception handling is in effect (i.e., EL3_EXCEPTION_HANDLING=1), Non-secure interrupts can't preempt Secure execution. However, for yielding SMCs, preemption by Non-secure interupts is intended. This patch therefore adds a call to ehf_allow_ns_preemption() before dispatching a Yielding SMC to TSP.
