RAS/AMD/ATL: Add missing newline to pr_info() statement

RAS/AMD/ATL: Add missing newline to pr_info() statement

Add a missing newline character even if printk() adds newlines to
non-\n-terminated strings because in the unlikely case a KERN_CONT print
statement is added after the unterminated statement, the two will get
glued together which is not the expected behavior.
