Use less generic defines for NGG enums to solve the problem.

Those that can would fail to clean up things if they actually got interrupted.

In fact, when the external GPU is runtime suspended, vga_switcheroo will cut power to the internal discrete GPU, resulting in a lockup. Moreover AMD's Windows driver special-cases Thunderbolt as well.
