histogram: enable histogram events

Use the sde-drm library to add the properties that generated
histogram interrupts into the atomic commital. This enables
the generation of the histogram events once the vndservice call
listed below is made. HWC hooks into control to follow
(i.e. currently HWC cannot turn feature on).
