[PATCH v1 1/1] serial: 8250_aspeed_vuart: Use dev_err_probe() instead of dev_err()

[Andy Shevchenko]

The probe process may generate EPROBE_DEFER. In this case
dev_err_probe() can still record err information. Otherwise
it may pollute logs on that occasion.

This also helps simplifing code and standardizing the error output.
