The A5 references sprinkled throughout the hw manager will no
longer make sesne within the context of two possible processors.
We will instead prefer the more generic "icp" term to reference

Note that some references to A5 remain and will be cleaned up
when LX7 is introduced.

Handle request abort cases from underlying hw mgr, hw layers.
This will handle in differentiating ERROR vs ABORT returned
from firmware in case of ICP and signal the fence accordingly.
By the time flush is issued to firmware, if a request is not
yet processed, firmware signals with Abort, which needs to be
propogated as CANCEL instead of ERROR to core context layer
so that context layer signals the fence accordingly as
ERROR or CANCEL.

Do not rely on timer expiry to remove bw of current context
if it is getting released. If context release is coming
before timer expiry (from last request submit), we are not
removing current context's vote from hw mgr and thus
from cpas. This will accumulate the bandwidth and causes
clocks to go to turbo and also into overflow issues if
the bw variables in cpas are wrapping around in long
hours testing.

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.
