Jeff Tinker da002fe641 Reorganize drm hal modules
Previously the drm and crypto plugins were separate hals.
This implied a separation of implementation libraries which
causes problems for some drm schemes. The reorganization
combines the hals into a single interface under drm.

Tests: basic gtests passing
