drm/i915/sdvo: Add dot crawl property
This property is slightly unusual in that it is a boolean and so has no GET_MAX command. Reference: Bug 28636 - missing TV parameter "Dot Crawl freeze" https://bugs.freedesktop.org/show_bug.cgi?id=28636 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
