disp: msm: sde: add hw catalog parsing for dnsc_blur block

Selaa lähdekoodia 
Add device tree parsing code for downscale blur block and sub blocks.
Add restrictions to allow downscale blur block to be used only by the
writeback. Set allowed interfaces for the block while parsing from
device-tree to restrict usage.
