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 the
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 information for NRT devices; JPEG,
LRME, FD and ICP.
For LRME, FD, JPEG context information is dumped.
FOR ICP, fw image is dumped.

When the userspace issues flush, ISP driver needs to ensure that
wait and active list requests are flushed and corresponding
buffer fences are signaled with error. For active and wait lists
IFE hardware is stopped immediately. Therefore IFE must also be
reset to ensure that VFE BUS FIFOs are cleared. Start IFE HW
after receiving init packet again.
