disp: msm: dsi: refine the logic for mode filling and calculation

Bläddra i källkod 
Video and command mode will be included in same timing node
when POMS is enabled, but DFPS is only applicable for video
mode, so add this change to differentiate panel mode, and fill
display mode according to panel mode.
