[RFC 05/11] drm: split property values out

[Rob Clark <rob.clark@linaro.org>]

From: Rob Clark <rob@ti.com>

Split property values out into a different struct, so we can later
move property values into state structs.  This will allow the
property values to stay in sync w/ the state updates which are
either discarded or atomically committed.
