dt-bindings: net: sophgo,sg2044-dwmac: Drop status from the example

Examples should be complete and should not have a 'status' property,
especially a disabled one because this disables the dt_binding_check of
the example against the schema.  Dropping 'status' property shows
missing other properties - phy-mode and phy-handle.
