disp: msm: sde: trigger a suspend commit if display in video mode

When there is runtime PM suspend and a video mode panel is Doze
state or Doze suspend state PM suspend will fail as clocks are on.
To avoid this do a suspend commit while entering runtime PM suspend
so that xo shutdown will be successful.
