resmgr: add release() methods
This makes the ResourceManager class much more functional
for uses where the set of resources used to scan out a
scene changes from frame to frame. The atomic modesetting
API discipline requires a brute-force search to find a
compatible pairing of planes/etc, and being able to reserve
bits incrementally is much simpler than throwing out the
entire resourcemanager and make a new one each time a
resource reserved in a tentative attempt to probe its
compatibility with an test-mode atomic commit, turns out not
to pan out.
