drm/panel: add support for the Visionox VTDR6130 AMOLED DSI panel

Add support for the 1080x2400 Visionox VTDR6130 AMOLED DSI panel
found on the Qualcomm SM8550 MTP board.

By default the the panel is configured to work with DSI compressed
streams, but can work in uncompressed video mode since 1080x2400 in
RGB888 fits in the 4 DSI lanes bandwidth.

While display compression is preferred for performance and power
reasons, let's start with the uncompressed video mode support and
add the DSC support later on.
