msm: camera: cdm: Add support for different CDM hardware

Browse Source 
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.
