firmware: stratix10-svc: add FCS polling command

Browse source

Introduce a new SMC command INTEL_SIP_SMC_FUNCID_SERVICE_COMPLETED
that polls if a previous asynchronous command was completed. This
SMC command is used by the new FPGA Crypto Service (FCS).
A basic example is that the FCS sends an AES data encryption
call to the secure device manager(SDM) and waits for the completion
of the operation by continuously polling the results with the new
command.
