Set primary mixer stages to 1 to force getting no blend
support from the display HAL.
This switches us from the SDE composition to the GPU
composition, which is a hack that is required for legacy
platforms on the SDE driver because of a severe
incompatibility with the current blobs.
There are no barriers because the FBDEV driver-HAL
combo have no blobs to support the SDM composition
and this configuration is anyway already doing what we
are forcing there.
