[PATCH v5 07/26] drm: sun4i: de3: add formatter flag to mixer config

[Ryan Walklin]

From: Jernej Skrabec <jernej.skra...@gmail.com>

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.
