When the avdd-0v9 or avdd-1v8 supply are not yet available, EPROBE_DEFER is returned by rockchip_hdmi_parse_dt(). This causes the following error message to be printed multiple times:
dwhdmi-rockchip fe0a0000.hdmi: [drm:dw_hdmi_rockchip_bind [rockchipdrm]] *ERROR* Unable to parse OF data
Fix that by not printing the message when rockchip_hdmi_parse_dt() returns -EPROBE_DEFER.
