drm/msm/dsi: Refer to connected device as 'device' instead of 'panel'
We currently support only panels connected to dsi output. We're going to also support external bridge chips now. Change 'panel_node' to 'device_node' in the struct msm_dsi_host and 'panel_flags' to 'device_flags' in msm_dsi. This makes things sound a bit more generic.
