drm/bridge: microchip-lvds: fix bus format mismatch with VESA displays

The LVDS controller was hardcoded to JEIDA mapping, which leads to
distorted output on panels expecting VESA mapping.

Update the driver to dynamically select the appropriate mapping and
pixel size based on the panel's advertised media bus format. This
ensures compatibility with both JEIDA and VESA displays.
