drm/msm/dpu: Only enable DSC_MODE_MULTIPLEX if dsc_merge is enabled

Browse source

When the topology calls for two interfaces on the current fixed topology
of 2 DSC blocks, or uses 1 DSC block for a single interface (e.g. SC7280
with only one DSC block), there should be no merging of DSC output.

This is already represented by the return value of
dpu_encoder_use_dsc_merge(), but not yet used to correctly configure
this flag.
