MLK-19318 drm/imx: lcdif: avoid log print when no device attached

In the 'lcdif_crtc_atomic_check()', when the 'bus_format' is
zero which means that there is no valid display peripherals
attached to LCDIF, return directly to avoid below error log
to make noises, since the error log is not cared in this case.
