[PATCH 02/18] AT91: setup: Switch to pr_fmt

[Maxime Ripard <maxime.ripard@free-electrons.com>]

Most of the printed messages are using the "AT91:" prefix in the setup.c file,
but not all of them. Moreover, those who add it hardcode it directly in the
message, while the pr_fmt macro makes it easier for us to support such a case.
