drm/komeda: Enable writeback split support
Writeback split is also for workaround the size limitation of d71 scaler.
Like layer_split, writeback downscaling also can use two scalers to handle
the scaling half-by-half. The only differnence is writback needs a
standalone component (splitter)'s help to split the composition result.
The data pipeline of writeback split as below:
/-> scaler-0 ->\
compiz -> splitter merger -> wb_layer -> memory
\-> scaler-1 ->/
v2: Rebase
