drm/etnaviv: reap idle softpin mappings when necessary
Right now the only point where softpin mappings get removed from the MMU context is when the mapped GEM object is destroyed. However, userspace might want to reuse that address space before the object is destroyed, which is a valid usage, as long as all mapping in that region of the address space are no longer used by any GPU jobs. Implement reaping of idle MMU mappings that would otherwise prevent the insertion of a softpin mapping.
