At the time of commit 9a643c9a11259955 ("sh-pfc: Convert message
printing from pr_* to dev_*"), the dev_*_once() variants didn't exist
yet, so the once behavior was open-coded.
Since commit e135303bd5bebcd2 ("device: Add dev_<level>_once variants")
they do, so "revert" to the good practice of using a helper.

To be queued in sh-pfc-for-v5.4.
