bdk: display: fully streamline dc/win setup

Browse Source 
As explained before, Nvidia just grabbed the whole dynamic init and made arrays
of it, without actually optimizing it.
The second part of the streamline aims to fully de-duplicate that.
- Completely remove all already set registers for DC/DISP/WIN.
- Do not touch other windows when a specific window is setup.
- Init Window D also together with A/B/C since code is made for DISPA.
- Add missing increase for syncpt 1.
