drm/panel: Enable DSC for Visionox VTDR6130 panel
Enable display compression (DSC v1.2) for 1080x2400 Visionox
VTDR6130 AMOLED DSI panel.
This panel is the default panel for the following devices:
- SM8550-QRD
- SM8550-HDK
- SM8650-QRD
- SM8650-HDK
Enable DSC since now functional in the MSM/DPU/DSI driver.
