misc: rk628: lvds: Add support for media bus format dt-bindings

Browse Source 
In previous versions, the bus-format of lvds could be set with prop
"vesa_24", "jeida_24", etc.

In order to maintain consistency with the panel node, this patch adds
support to for set bus-format via the `MEDIA_FORMAT` number macro.

rk628-lvds {
	/* Equivalent to
		bus-format = "vesa_24";
	*/
	bus-format = <MEDIA_BUS_FMT_RGB888_1X7X4_SPWG>;
};
