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.

Currently sync driver is independent from dtsi matching in order
to get it probe. Update the logic to make sure probe is getting
invoked if respective dtsi is present.

The v4l2 registration requires all devices that are not subdevs
to have device caps field to be non zero. Add device caps for
CRM and SYNC devices during probe.

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.

Kernel uses v4l2 events to communicate with userspace.
If userspace is not dequeuing events and kernel is pushing more events
then v4l2_event_queue fails silently.
This change uses v4l2 callbacks to log v4l2_event_queue failure.

EIS have 6 fences per request and uses 15 frame window. On camera close
it signals ~90 fences at once. This can overflow v4l2 event queue.
Increase v4l2 queue length for sync events to prevent overflow.

Synx driver is dependent on camera driver for registering callback
functions of sync driver. This change invert the logic, and camera
driver will register the callback functions for synx driver at the
time of sync driver probe.
