pinctrl: at91: Use dev_err_probe() instead of custom messaging

The custom message has no value except printing the error code,
the same does dev_err_probe(). Let's use the latter for the sake
of unification.

Note that some APIs already have messaging in them and some simply
do not require the current noise.
