In future, more parts of OpenSBI will use the extra scratch space so it will become difficult to manage extra scratch space using just defines and macros. This patch adds a simple brain-dead allocator to manage extra scratch space. This allocator never expects anything to be free-ed hence it keeps incrementing to next allocation offset until it runs-out of space. In future, we can have more sophisticated allocator which will allow us to re-claim free-ed space and also allows us to track owner of allocated space.
