implement mali specific sw fence in kbase

Project Member Reported by dbehr@chromium.org, Aug 2 2017

Issue description

Right now we are using something based on timeline fence which a debug only fence upstream and not available for drivers to inherit from.

So we need to implement software fence that is based on dma-fence only.
It needs to have some timeline fence properties (all fences should be signaled when the context (aka timeline) is destroyed). Also mali kbase requires fences to be always signaled in creation order without skipping any.
