Storing config space during sysman init might result in
providing inappropriate properties as config space can be
modified.
Read config space whenever properties are queried.

This change helps in achieving the following:
- Moves the OS specific code from scheduler_imp.cpp to os specific
files.
- Frees any drm resource, including level zero's before enabling/dis
-abling Debug mode. And once Debug mode is toggled, reinitialize of
level zero occurs.
- If current mode is Debug mode and any other mode is requested by user,
then new mode will be made effective by unsetting debug mode.

Earlier implementation of sysman events API was based on file
creation in the filesystem. Whenever a uevent for some event
which needs to be monitored arrive, at that time a file was
created in the filesystem based on some preinstalled udev rules.
This approach was inefficient as it heavily depends over file
system and second with this approach losing events is always a
possibility.
Now with this change, we are removing our dependency over file
creation in filesystem. Rather we will be using libudev library
to monitor the uevents. This approach could also be extended,
when we want to listen to all the uevents for all the gpu
devices present in the system.

This patch makes iaf nl interfaces in sysman be usable
by other modules.
1.change Iaf_nl interfaces to remove sysman dependencies
2.move iaf specific interfaces(getPorts()) to iaf specific file
3.move iaf_nl files to sysman/linux

The following modifications were done as part of the fix
for warm reset.
1. Release sysman resources before quiscenting the GPU.
2. Add additional checks to confirm quiscenting of the GPU
before launching the diagnostics tests.
3. Fixed warm reset with wait time to allow the changes to be
propagated to the entire GPU PCI tree.
4. Modified the ULT's completely to avoid the usage of MOCKS.
5. Made Diagnostics handle creation per-device from per-SubDevice.
