disp: msm: sde: extend topology_control to reserve dnsc_blur

Extend the topology_control connector property to support downscale
blur block. This gives user-mode the capability to reserve the downscale
blur block. Add sde rm changes to reserve the block based on this
connector property during sde_rm_reserve.
