drm/vc4: hdmi: Don't poll for the infoframes status on setup

Browse source

The infoframes are sent at a regular interval as a data island packet,
so we don't need to wait for them to be sent when we're setting them up.

However, we do need to poll when we're enabling since the we can't
update the packet RAM until it has been sent.

Let's add a boolean flag to tell whether we want to poll or not to
support both cases.
