On some platforms we need to trigger an extra async flip with the async flip bit disabled, and then wait for the next vblank until the async flip bit off state will actually latch. Currently the w/a is just open coded for skl+ universal planes. Instead of doing that lets reuse the .async_flip() hook for this purpose since it needs to write the exact same set of registers. In order to do this we'll just have the caller pass in the state of the async flip bit explicitly.
