Handle event failure reason propagation in camera kernel
driver. Individual camera kernel driver will fill reason
codes for sync failure and send it to sync driver. Sync
driver will add this as part of sync event header and
propagate to user space.

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 unlock frame_req_mutex until the request is added
into processing list after submitting the frame to hw.
This can cause a race condition where Flush comes before
adding the frame into processing list and thinks there
is no frame with HW. And there is a possibility that
FrameDone IRQ thread can get the mutex and thinks no frame
in processing list - causing never to reset the flag
ready_to_process. This will cause all subsequent camera
usage to fail as requests will never be submitted to hw.

The work data passed as payload to workq is statically allocated,
which has kfree call during destroy, this fails during component
unbind. Change allocation of work data to dynamic in fd hw manager.

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.

Due to the asynchronous nature of platform probes, inter
dependency between drivers needs to be taken care during
kernel boot up. Component helper provides the facility of
adding matching drivers in a list ordered in the way we want
to bind those drivers. The CRM driver acts as component master
to make sure all slave drivers are bound before it returns
from its own bind call. Add support for serializing platform
probes through component framework.

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.

Currently camera modules platform registration/remove function
is being called as a part of module_init function individually.
Building camera as module, current infrastructure cannot support
it, as DLKM only support single module_init/exit function.
This change enables that support by combining all platform
entry/remove functions centrally. Also, remove all submodule
makefiles and combined into one root makefile in order to generate
single kernel object file to dynamically loading the kernel module
in case of DLKM compilation.

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.
