From: Jernej Skrabec <jernej.skrabec@xxxxxxxxx>
Only the DE3 (and newer) display engines have a formatter module. This
could be inferred from the is_de3 flag alone, however this will not
scale with addition of future DE versions in subsequent patches.
Add a separate flag to signal this in the mixer configuration.
