[PATCH -next 4/5] usb: musb: jz4740: Switch to use dev_err_probe() helper

[Yang Yingliang <yangyingliang@huawei.com>]

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.
