drm/bridge: synopsys: dw-hdmi: fix no display between kernel logo and android logo

def_mode picture_aspect_ratio is no HDMI_PICTURE_ASPECT_NONE,
but Android set mode, the picture_aspect_ratio is HDMI_PICTURE_ASPECT_NONE,
When comparing the new mode with the old mode, the two are inconsistent,
so the mode will be changed.
