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 Change-Id: I5cde6ff9f60625a0219731c4dbfcaefbd9f27f88 related-to-bug: 32815560
