Different CDM hardware have different capability and registers. With old register space, handling new features and operations would have been a complex task. This change takes care of old version of CDM and also changes the regspace to provide every register's access to CDM. This change further adds support for "arbitration" in case of multi-context CDMs. Exports reset functionality to clients, detection of CDM hang. Flushing the CDM requests and dumping the FIFO content for all contexts. It also adds submitting "debug_gen_irq" as BL_done IRQ is only an indication for availability of FIFO's. The AHB operations are completed can only be known if the added "debug_gen_irqs" gets executed and are received by the CDM.
