MLK-21407 gpu: imx: dpu: tcon: Assign tcon id

We should assign dedicated id for every tcon instance.
This makes us be able to figure out bewteen master and
slave tcon.  Only side-by-side display mode is likely
impacted.  Based on tests, no functional change is
observed before or after this patch is applied.
