drm/i915: avoid full modeset when changing the color range properties

Automatic color range selection was added in

commit 55bc60db5988c8366751d3d04dd690698a53412c

    drm/i915: Add "Automatic" mode for the "Broadcast RGB" property

but that removed the check to avoid a full modeset if the value is
unchanged. Unfortunately X sets all properties with their current
value at start-up, resulting in some ugly flickering which shouldn't
be there.

v2: Change old_range from bool to uint32_t, spotted by Ville.

v3: Actually git add everything ;-)
