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.
