[PATCH][v3] dt-bindings: ifc: Update endianness usage

[Prabhakar Kushwaha <prabhakar.kushwaha-3arQi8VN3Tc@public.gmane.org>]

IFC controller version < 2.0 support IFC register access as
big endian. These controller version also require IFC NOR signals to
be connected in reverse order with NOR flash.

IFC >= 2.0 is other way around.

So updating IFC binding to take care of both using endianness field.
