Add support for lock/unlock on bam pipe in sha. If multiple EE's(Execution Environment) try to access the same crypto engine then before accessing the crypto engine EE's has to lock the bam pipe and then submit the request to crypto engine. Once request done then EE's has to unlock the bam pipe so that others EE's can access the crypto engine.
