[PATCH] arm: dts: imx53: Fix LDB OF graph warning

[Rob Herring]

Single child nodes in OF graph don't need an address and now dtc will
warn about this:

Warning (graph_child_address): /soc/aips at 50000000/ldb at 53fa8008/lvds-channel at 0: graph node has single child node 'port at 0', #address-cells/#size-cells are not necessary

Since the LDB should always have an output port, fix the warning by
adding the output port, 2, to the DT.
