sdm: set single LM topology for 1080p panels.

Driver do not populate topology in connector info
before NULL commit. SDM assumes dual LM topology during
initialization which leads to less clock voting and 
underrun on 1080p panels.

Set single LM topology for 1080p panels. This is stop-gap 
solution till driver expose topologies for all modes upfront.
