Use dev_err_probe() to log errors in the probe function of all drm mediatek drivers. This avoids -EPROBE_DEFER return values from being logged as errors, like the following: mediatek-disp-rdma 1c002000.rdma: Failed to add component: -517 As a side benefit it also standardizes the format of the error in the log messages.
