Monitor sync object operations such as create, register callback,
signal, unregister callback which is useful in debugging. Introduce
debugfs to dynamically set the monitor mask. Apply dump on error
when CAM_GENERIC_FENCE_TYPE_xx is set in cam_sync_monitor_mask and
apply dump on release when CAM_GENERIC_FENCE_TYPE_xx_DUMP is also set
at the same time. Apply dynamic memory allocation for monitor data
in synx and dma. Refactor APIs into generic ones and add memory
checkings.
