Update the cdm submit bl function to use allocated
genirq memory for genirq command instead of appending
the command to the last BL entry to prevent possibly
using the memory not mapped. Also, add some more logs
to make the debugging easier.

Add a check for reg-val count=0 in reg_random command. Count=0 in
reg_random cdm command will throw an invalid command HW error.

CDM comp_wait is the new cmd_type used by IFE Master
to wait for trigger from slave. Add this type to
the dump command buffer routine.

If there is a stale entry of any event in the CDM,
it will end the wait of same event in next request.
So, clearing the comp events before each request.

When user space detects an error or does not receive
response for a request, Lets do a reset(LDAR) is triggered.
Before LDAR, user space sends flush command to the
kernel space.
In order to debug the cause for this situation and to dump
the information, user space sends a dump command to
kernel space before sending flush.
As a part of this command, it passes the culprit request id
and the buffer into which the information can be dumped.
Kernel space traverses across the drivers and find the culprit hw
and dumps the relevant information in the buffer.
This data is written to a file for offline processing.
This commit dumps the IFE, CSID registers, LUT tables and context
information, cmd buffers, timestamps information for
submit, apply, RUP, epoch and buffdones of the last 20
requests.

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.
