[PATCH 6/7] phy: qcom-qusb2: Use dev_err_probe() to simplify code

[Yuan Can]

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.
