msm: mdss: enable right-only update on DUAL_LM_SINGLE_DISPLAY split mode

Any smart panel with DUAL_LM_SINGLE_DISPLAY split mode with support for
partial update requires runtime topology changes when update is using
only one layer mixer. Specifically, when right-only partial update is
needed, MDP topology needs to switch to ping-pong associated with right
layer mixer and disable left layer mixer path. Add changes to support
these use-cases dynamically.

Now when Display Stream Compression (DSC) is used with this split mode,
there are certain restriction from HW when switching from left+right
update to right-only update. During such scenarios we cannot use right
layer mixer based data path and have to use left layer mixer based
data path. Add quirk based logic to use this mode.
