mb/lenovo/*/acpi_tables: Remove comment about IGD displays

IGD display handling was rewritten with commit dd2bc3f8 with Change-Id
I556769e5e28b83e7465e3db689e26c8c0ab44757 ("igd.asl rewrite"). These
comments were removed as well (with some accidentally left behind).

Let's remove them and those who were introduced later with new ports.
