Subject: [PATCH] ARM: atags: Be silent about missing ATAGs

From: Paul Kocialkowski <contact@...lk.fr>

While the ATAGs functionality is still available in the kernel, it has
been deprecated for a long time already and probably has very few users
left.

Stop printing a message when ATAGs are not found since this is now the
situation most users will expect.
