drm: msm: handle resolution switch for LTM 



DPU configuration should be changed when resolution switch happens at
the layer mixer level for ltm feature. Driver should mark ltm properties
as dirty when resolution switch happens. Change handles dynamic resolution
switch for ltm by marking the properties as dirty.
