disp: msm: sde: expose dnsc_blur connector properties

Browse Source 
Add downscale blur connector properties to expose the hw block count,
downscaling filters used and the ratios supported. Add a custom dnsc_blur
property to allow usermode to send the required configuration to program
the hardware. Expose only for the virtual connector as the dnsc_blur is
only supported with writeback block.
