Subject: [PATCH] drm/msm/dpu: Use the encoder for default CRC source

From: Rob Clark <robdclark@...omium.org>

i-g-t expects the CRC to reflect any applied CTM.  But the layer mixer
source is upstream of the DSPP, so it is before the CTM is applied.

Switch the default source to 'encoder' instead so that the CRC is
captured downstream of the DSPP.
