drm/msm/sde: update drm modes with private fields during atomic check 



display drivers can populate private fields of the drm display mode
structure while registering possible modes of a connector with
DRM. These private fields are not populated back while DRM invokes
the mode_set callbacks. This change retrieves and populates the
private fields of the given mode during encoder atomic check.
