[PATCH] power: supply: bd71828: Use dev_err_probe()

[Matti Vaittinen <matti.vaittinen@linux.dev>]

From: Matti Vaittinen <mazziesaccount@gmail.com>

The driver uses separate error printing and error returning at probe()
for locations where the error value is hard-coded and can't be
EPROBE_DEFER. This helps to omit the extra return value check which is
done in dev_err_probe().

Using the dev_err_probe() has some other benefits besides handling the
-EPROBE_DEFER though, like standardizing the print for error numbers.
Some believe thes outweigh the benefit of skipping the extra check.

Use dev_err_probe() consistently in the bd71828 power-supply probe.
