Subject: [PATCH v2] pmdomain: imx: gpcv2: replace dev_err() with dev_err_probe()

The patch standardizes the probe() code by replacing the two occurrences
of dev_err() with dev_err_probe(). Indeed, dev_err_probe() was used in all
other error paths of the probe() function.
Note that dev_err_probe() has advantages even if the error code is not
EPROBE_DEFER, such as the symbolic output of the error code. Therefore,
it should generally be preferred over dev_err().
