Jeenu Viswambharan 1dd022ca6a 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.
