The error handling in dw_hdmi_qp_rockchip_bind() is quite inconsistent,
i.e. in some cases the error code is not included in the message, while
in some other cases there is no check for -EPROBE_DEFER.
Since this is part of the probe path, address the aforementioned issues
by switching to dev_err_probe(), which also reduces the code a bit.
