devicetree: bindings: Update DT binding doc

Browse Source 
- Fsi, generic and VPR carveouts follow the reserved-memory DT binding
provided by linux kernel. Hence delete these unnecessary DT binding files.
- Rename nvidia,carveouts-t19x.yaml file to nvidia,carveouts.yaml
- Update compatible string for tegra-carveouts.
- Add missing properties like disable-debug-support, memory-region for
tegra-carveouts.
