crypto: engine - Introduce the block request crypto engine framework
Now block cipher engines need to implement and maintain their own queue/thread for processing requests, moreover currently helpers provided for only the queue itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they don't help with the mechanics of driving the hardware (things like running the request immediately, DMA map it or providing a thread to process the queue in) even though a lot of that code really shouldn't vary that much from device to device. Thus this patch provides a mechanism for pushing requests to the hardware as it becomes free that drivers could use. And this framework is patterned on the SPI code and has worked out well there.
